Jeep Low Beam Headlights Not Working? The 127 Detailed Answer

You may be wondering what exactly are headlight relays and what does it have to do with car headlight restoration? It’s okay to admit not being overly familiar with car terminology and jargon. That’s why we exist to break them down into simpler and simpler forms so you can understand them and make informed decisions.

So headlight relay switches basically refer to the electrical components that break the flow between the conductors by an electromagnet that controls and activates the headlights and is responsible for deactivation and brightness.

There can be multiple reasons why your relays may be bad, just as there are multiple factors that necessitate cleaning your headlight lens. It is important to pay careful attention to all these tips, fixes, and symptoms that we have compiled in this article.

The relays in your car are very important to the headlight form and function. So if your relays are bad it can be pretty serious, but it doesn’t have to be. Luckily, there are several signs and symptoms that the relays give before they fully kick off. The key is to take proactive action and you will be fine.

Symptoms of a bad headlight relay

Headlight doors do not give way:

This is one of the first and most common signs that your relay is faulty. If your headlight doors won’t budge or open, it’s because the relays aren’t generating enough current to open the headlight door. However this does not mean that the headlights will not turn on, they can be but the headlight shutters will not open and thus bypassing the reason for the headlights not providing any light to the driver.

Headlight flaps can be stuck open

This is essentially the opposite of the first symptom. Here the headlights can be switched on, the doors are also open. The driver can see, but the headlights cannot close. Now this may not be a big problem and most drivers may choose to ignore it as at least the headlights work, but this is an indication of a bigger problem – a bad relay and therefore requires immediate attention.

Headlight doors have a mind of their own

Another indication that your relays need your attention is when the headlight flaps seem to have a mind of their own, opening and closing erratically. This is actually a huge and very dangerous problem as it can very well lead to accidents and collisions. You don’t want to be a driver with this problem at night. Potentially catastrophic!

Now the question remains how can we find solutions to problems with headlight relays. There are so many sub-questions – do you have to see a mechanic or a specialist? Are you paying a hefty sum? How long it will take? Is it a difficult task? Well, repairing or replacing your headlight relay is easier and simpler than you think and the best part is you can do it yourself?

5 DIY steps to replace a faulty relay

Find the termination of the headlight relay:

Obviously the first thing to do when replacing your faulty relay is to remove the faulty one so that you can repair it in the new one. If you are unsure of the exact location of the relay, consult your vehicle’s owner’s manual. It’s usually under the hood of the car. The point where your fuse box is most likely located.

On the other hand, it can also be located in the cab of the car, this would be the case if your car is equipped with an internal fuse box. You may also want to learn how to clean the inside of a sealed headlight to get a better beam.

Remove the fuse cover/cover

Now that you’ve found the fuse box. You should carefully remove the cover or lid so that you can reattach it properly

Take out the old relay

The headlight closure relay is pulled directly from its terminal. If it’s hard to get a hold of, you can use pliers, a needle tip, or something else. Make sure it is the same relay type as the replacement relay.

Once you gently pull, the headlight close relay would disengage from its terminal. However, sometimes it can be difficult to pull it off. If this happens, you can pry it open with pliers. Make sure you use the two relays though – old and new are in the same style.

Insert the new relay.

Now you can insert the new relays up to where you removed the old ones. Make sure you press it down firmly so it can connect properly.

Test the headlights and cover the fuse box.

If you installed a new headlight relay, your headlights and headlight flaps should be working properly. After that, you can carefully close the fuse box, and voila!

Conclusion

Now you know how to recognize when your relays are bad and now you know how to fix the situation and finally clean your headlights at home.

You should be aware that taking care of your headlights and relays is absolutely essential and essential to driving more safely and keeping the roads safe for you, other cars and other pedestrians.

A good driver is one who not only drives for himself but also for the benefit and safety of others. It’s also worth paying more attention to your headlight flaps and signals so you don’t get stuck in a problem phase before it’s too late.

While the steps for changing or replacing headlight relays are relatively simple and easy enough to do yourself, it’s still okay to read the vehicle’s manual for guidance and you’ll be instructed accordingly. Your car covers should not be left out as you should know how to clean plastic headlight covers.

You can also choose to hand the vehicle over to an expert who will help with the relay replacement. It’s better to be safe than sorry, and it’s better to give to someone who knows what they’re doing than risk harm yourself.

07 Jun How much does it cost to repair car headlights?

Whether you need to repair car lights for aesthetic reasons or you need better visibility on the road to avoid potential hazards, one thing is certain: cost is often a primary concern for car owners. And why shouldn’t it be an important factor in decision-making? Choosing the wrong headlight bulb of inferior quality or choosing one that doesn’t fit your vehicle can waste your money.

Repair headlights – how much does it cost?

Regardless of the make and model of the car, headlights are an integral part of it. You may not notice them until they begin to fade or burn out completely. When they fade, you suddenly find yourself in the new headlight market. But before you make a purchasing decision, let’s understand the average cost associated with headlight repair.

Problem: One of the headlights needs repairing

If one of the headlights is working properly and the other is having problems, it usually means that the bulb has burned out. Lightbulbs have a limited lifespan. And if you regularly use the car for night driving, the lamps will quickly go out.

Solution: Replace the light bulb to solve the problem

If you just need to replace the headlight bulb, it can cost you $15 for a set of halogen replacement bulbs. If you choose HID replacement bulbs, you may have to pay more depending on the type of bulb you need. For example, 9005 3700 lumen HID replacement bulbs are available online for $39.99. LED bulbs are available under $50.

If one of the light bulbs has failed, it is possible that the other will soon go out. For an even view on the road, it is best to replace both lamps. Also, don’t forget to factor in the labor and installation costs involved. Depending on the complexity and the number of hours it takes to get the job done, your local mechanic may charge you $50 or more.

Problem: Both headlights do not work

If both headlights don’t work, it will be difficult to drive the car at night. It means inviting potential accidents and putting your life at risk. If the headlights don’t work, you need to fix the problem immediately.

Solution: Visit a mechanic today

In such a situation, burnt out lightbulbs are hardly the cause of the problem. There can be several reasons why the headlights fail. It is best to take your car to an experienced mechanic to clearly understand the problem. Find a reputable mechanic who knows your car model inside out. Typically, the inspection costs $50.

It is possible that the fuse has blown and needs to be replaced. Wiring can become damaged over time. It can cost you $100 an hour. The cause of the problem may be a defective headlight switch. If the headlight only works with high beam or low beam, the dimmer switch is often defective. The average cost of replacing the headlight switch or dimmer switch is in the $150-$250 range.

Problem: Headlight is broken and damaged

Sometimes accidents can damage the headlight and you are left with no choice but to replace the entire assembly. It can be a costly affair and you may have to spend a few hundred dollars to pay for new headlights.

Solution: Replace the headlight assembly

The cost of replacing the entire headlight assembly can vary phenomenally depending on the make and model of the vehicle and also whether you have a sedan, pickup truck or SUV. A quality headlight assembly can range in price from $250 to $700. And if you have LED headlights in your car, your costs can increase even further. If the price bothers you, look online for the best deals at affordable prices.

Most new car models have headlights that come with multiple fasteners and screws, making it difficult to replace the entire assembly. So you may need to pay $150 for installation.

Problem: Insufficient lighting on the street

If the headlights are not working optimally, your visibility on the road will be affected. It is very dangerous to drive such a car at night or in bad weather.

Solution: Update the headlights

If the problem is dirt or moisture in the headlight housing, it can be easily removed. But when the car uses old technology, it’s time for an upgrade.

You can choose new technologies like HID headlights and LED headlights over the old halogen bulbs. Go online to find high quality, reliable HID conversion kits and LED plug and play replacement headlights to upgrade your car’s lighting. An HID conversion kit is easily available in the $100-$180 range. LED headlights may be a bit pricey, but their ability to last a very long time makes up for the price.

Changing Car Headlights: Making an Affordable Decision

Ignoring the dim headlights not only means you risk hefty fines from local authorities, but you also put your safety at risk. There are many affordable car lighting options on the market. Consider choosing headlights based not only on price, but also on durability. So forget the dim, blurry yellow lights and say yes to bright vision on the road.

Whether you need direct replacement bulbs, LED headlights or HID conversion kits for your car, shop at Underground Lighting. The reliable car lighting store offers great deals on all types of car lamps. Free shipping over $99.

Headlights are essential and driving without them is becoming increasingly dangerous. If your high beam works but the low beam does not, there can be several reasons. While it’s easy to assume that this is due to a bad lightbulb, if changing the lightbulb doesn’t help, there may be a deeper problem at hand. Don’t neglect this problem by driving during the day. Driving without headlights is not only dangerous; It’s illegal. You might come out of pocket for a fix-it ticket. Listed below are 3 of the most common issues that cause the high beams to come on while the low beams remain inactive.

The relay is damaged

In layman’s terms, a vehicle’s relay is a switch that operates electronically. If the relay is faulty, it may receive power but will not be able to complete the full circuit. A new relay is required for this. Some vehicles have different relays for high beam and low beam. If one relay breaks, the other can still work to power the light.

A fuse has blown

As soon as you notice that an electrical component is not working, first check the associated fuse. Your vehicle’s owner’s manual will indicate which fuse corresponds to each item. If a fuse is blown, replacing it should fix the problem. Inspecting fuses can be intimidating; If you’re concerned, bring your vehicle in to have one of our experienced mechanics check the fuses for you.

There is a problem with the wiring

Wiring within a vehicle is incredibly complex. Fuses can blow due to incorrect wiring. While a blown fuse can be a one-time occurrence, it can indicate underlying wiring issues that need to be addressed. Replacing the fuse is only a temporary fix if the wiring is damaged. It is important that you rely on your trusted auto mechanic to properly address this issue to get you back on the road safely.

Your low beam is just as important as your high beam. If the low beam does not work, there is an increased risk of accidents. Prestige Auto Works is the premium dealer alternative. We work on all vehicle makes and models, specializing in Mercedes-Benz, BMW and GM

3. Wiring problem

The wiring in your car is complex, and faulty wiring can cause the headlights to not work. In fact, wiring problems can also cause a fuse to blow, since fuses will blow when an overcurrent flows through a system. If it’s a one-time problem, the fuse might just blow once. But if it’s due to an underlying wiring issue, the spare fuse won’t last either. Due to the complexity of the wiring in your vehicle, it is recommended that the diagnosis be left to the experts.

2. Damaged relay

When you flick a light switch in your home, the switch completes a circuit and turns on the light. Your car is a little different. The switch you flick doesn’t actually complete the circuit. Rather, it sends a little energy to a relay, and the relay completes the circuit. If the relay is faulty, it may receive power from the switch but will not be able to complete the circuit. In such cases a new relay may be required.

In some cases, high beam and low beam have separate relays. If one of these relays breaks, the other may still work.

Headlight technology is not very complex, but there are many different ways headlights can fail. So if you find that your headlights suddenly stop working, it’s important to note the type of fault you’re dealing with and work from there.

The troubleshooting process you follow depends on the type of error you are dealing with. With this in mind, it can be very useful to first check if both or just one of your headlights have failed and if the high or low beams are still working.

Common situations and fixes for headlights not working

Wire of Life / Luyi Wang

When the headlights stop working, there is usually an electrical problem or a physical problem with the bulbs themselves. In order to get to the bottom of the situation as quickly as possible, it is important to note exactly what type of outage you experienced.

Based on which lamps are no longer working and under what circumstances, you can use the following information to narrow down a solution:

A headlight does not work. The Cause: This is usually caused by a burned out lightbulb.

: This is usually caused by a burned out light bulb. The solution: replace the light bulb. If it still doesn’t work, suspect a wiring or fuse problem. HID (High Intensity Discharge) headlights can also fail due to other associated components. None of the headlights work. The cause: Blown light bulbs or a power or ground problem.

: Blown bulbs or a power or ground problem. The solution: Check for power and ground and fix if necessary. If not, replace the bulbs. Lightbulbs don’t usually burn out together, but it’s still important to rule this out by checking for electricity. Most total headlamp failures are caused by a bad component like a fuse, relay, or module. Wiring issues can also cause both headlights to stop working. High beam not working or low beam not working. The cause: A blown bulb or a problem with the high beam switch or relay.

: A blown bulb or a problem with the high beam switch or relay. The solution: Replace the bulb, switch or relay. If only one bulb works in either high beam or low beam mode, it may be the bulb. Most headlight failures that are limited to only high or low beam are related to a relay or the high beam switch. Headlights work but look dim. The cause: fogged lenses, worn bulbs or a problem with the charging system. The solution: clean the lenses, replace the bulbs or repair the charging system. If your headlights always seem dim, the problem could be fogged up lenses or worn bulbs. If your headlights appear to dim under certain circumstances, there may be a problem with the charging system. Other headlight problems are also caused by a combination of bad bulbs, wiring or relay problems, and bad switches.

How do headlights work?

Most headlight systems are fairly simple and involve a few basic components such as the bulbs, a relay, a fuse and a switch. There are variations on this basic theme, such as B. some vehicles with daytime running lights, adaptive headlights or other small folds like fog lights, but the idea is still the same.

When you turn on your headlights, this switch activates a relay. This relay, in turn, makes the electrical connection between your headlight bulbs and the battery. Fuses are also involved to provide a sacrificial point of failure to protect the rest of the wiring.

Just like your headlight switch activates a relay to power the headlights, operating your high beam controls generally activates a relay to turn on the high beams. In the case of dual filament headlight pods, this literally sends electricity to the high beam filament.

If any of these components stop working properly, your headlights will fail. And if you look at how they failed, you can usually go back to find out where’s the best place to start troubleshooting.

Fix it yourself or take it to a mechanic?

Fixing a blown headlight is usually pretty easy, but there are instances when you might want to go straight to a mechanic. If you don’t have some basic car tools and basic diagnostic tools, you might want to consider taking your car to a professional during the day.

When you take your car to a workshop, they will likely start with a visual inspection of the headlight system, checking your fuses and taking a look at the switches and relays.

Replacing a blown headlight usually only takes a few minutes, but the diagnostic process can take anywhere from half an hour to an hour, or even longer if you’re dealing with a more complicated issue.

The diagnostic procedure that a professional technician will actually perform is similar to that described below. So if you want to know more about what to expect when you bring your car in for headlight repairs, you might want to read on.

Fixing a bad headlight

If one headlight stops working and the other works fine, the problem is usually just a blown bulb. Even if both headlight bulbs have been exposed to exactly the same conditions, they usually don’t fail at exactly the same time. So it’s pretty common for one bulb to blow out before the other.

Before writing your headlight bulb off as bad, it’s important to inspect the electrical connector for signs of damage or corrosion. If the plug has come loose, plugging it back in may fix the problem. However, you should dig a little deeper to find out why it came loose in the first place.

Another factor to consider before replacing a blown headlight capsule is whether or not there were external causes for the failure. Conventional halogen capsules can last between 500 and 1,000 hours. So if yours didn’t last that long, there may be another problem at work.

A simple thing to look for is water or condensation in the headlight assembly. If the gasket is worn or damaged, or if the case itself is cracked, water can easily enter. When this happens, the life of your headlight capsule will be greatly reduced and the only solution is to replace the headlight assembly.

What to do if both headlights stop working?

If both headlights fail at the same time, the problem is usually not the bulbs. The main exception is when first one headlight burns out, goes unnoticed for some time, and then the other lamp also fails.

If you suspect the bulbs might be bad and you have a voltmeter, you should start troubleshooting by checking to see if the headlights are getting power. The best way to do this is to turn on the headlight switch, connect the negative lead on your gauge to a known good ground, and touch the positive lead to each headlight terminal.

One of the connectors should show battery voltage and the other two should show nothing if the problem is blown bulbs. You can then try activating your high beams, which should cause another terminal to show battery voltage. If this is the case, replacing the light bulbs should fix your problem.

Testing fuses, relays, switches and other headlight circuit components

The first and easiest component to check is the headlight fuse. Depending on how your headlight circuit is set up, there may be one fuse or multiple fuses for the headlights. If you find a blown fuse, replacing it may fix the problem.

When replacing a blown headlight fuse, it is important to use a new one of the same amperage. If the new fuse blows, it indicates a problem elsewhere in the circuit and replacing a higher amperage fuse could cause catastrophic damage.

If you find that the fuse is not blown, the next step is to check the power supply with a voltmeter. You should find battery voltage on either side of the fuse. If not, you need to look at the wiring between the fuse block and the battery.

The next step is to locate and check the headlight relay. If you pull and shake the relay and you hear something rattling inside, then it’s probably failed. Discoloration on the socket or connectors can also indicate a problem.

If you are lucky you will find that the same relay used in your headlight circuit is used in another circuit(s). In this case, you can easily replace the headlight relay with an identical component. If the headlights start working at this point, the relay was the problem.

In addition, the diagnostic procedure is somewhat more complicated. To determine if the relay or switch is faulty, you would need to check if the relay is receiving power when the headlight switch is activated. If it doesn’t, then there is either a problem with the headlight switch or the wiring between the switch and the relay.

If your vehicle has a headlight module, daytime running light module, or other similar component, the diagnostic procedures can be even more complex. In these cases, it is best to rule out all other components first.

How to fix not working low or high beam headlights

Many of the same problems that can cause headlights to stop working can also cause just the low or high beams to stop working. If you find that when you turn on the high beams, only one bulb goes out but the other works fine, the high beam filament in the first bulb has probably burned out. The same is true when an incandescent bulb is working on high beam, but now low.

In most cases, the high or low beam failure is due to a relay or switch problem and the troubleshooting procedure is similar to that outlined above. The difference is that some vehicles have a separate relay for the high beam only, and the high beam, low beam, or low beam switch may or may not be integrated with the headlight switch.

If you locate the high beam relay and find that it is not receiving power when the high beam switch or dimmer switch is activated, the problem is either with that switch or with the wiring. In some cases, a loose lever switch can cause this problem, although it is more common for the switch to fail completely.

What causes headlights to appear dim?

When headlights stop working, they generally stop working. There are some situations where you may find that your headlights don’t appear as bright as you expect, but the cause may or may not actually be headlight related.

If your headlights always seem dim or don’t seem to illuminate the road properly, there are a handful of factors that could be at play. The first is that headlights actually lose brightness as they age. So if it’s been a long time since you’ve replaced your headlights, a brand new set of bulbs can shed some light on your problem.

Dirty, fogged up, or oxidized headlight lenses can also cause a problem by blocking some of the light. Dirt is easy to see and clean, while fogged lenses usually indicate water intrusion into the headlight assemblies.

While it is sometimes possible to drill a small hole in a headlight assembly to drain water, this may not be a permanent solution. In some cases, you may actually need to replace the headlight assembly.

Oftentimes, you can fix headlight lens cover oxidation with a headlight rebuild. This is a process where the oxidation is removed with an abrasive and then a protective clear coat is applied.

Problems with headlights and electrical systems

If your headlights appear dim when the engine is idling and seem to vary in brightness with RPM, then the problem may be with the electrical system. The most common cause is a bad alternator or a loose belt. If you find that your battery voltage is below 13V with the engine running, you should check the charging system before worrying about the headlights.

In some situations you may find that the charging system is working properly but still cannot keep up with the demands of the electrical system. This is usually due to the installation of power-hungry aftermarket components, like a custom sound system with a powerful amplifier.

When the charging system isn’t keeping up with the demands of aftermarket components like amps for your vehicle, the dashboards and headlights are often the easiest sign to spot. If you notice your headlights or dash dimming to the beat of your music, or when you’re stuck in traffic, a stiffener cap or more powerful alternator may fix the problem.

Additional issues with HID headlights

Traditional halogen headlight failure is usually fairly straightforward, but things can get more complicated when you’re dealing with xenon or HID headlights. While it’s possible for an HID bulb to burn out, there are several other potential sources of failure that you need to consider. The bulb may have burned out, or the problem could be related to a bad ignitor or a wiring issue.

The easiest way to check if your HID headlight capsule is bad is to carefully remove both bulbs and replace the non-working one with the working one. If the known-good lightbulb doesn’t turn on when placed in the other socket, you’re dealing with a more complicated problem.

It is important to note that when replacing the bulbs, to rule out a problem with the ignitor or wiring harness, you must avoid touching the glass envelope of the capsule. Any oils or other contaminants from your hands or elsewhere will greatly shorten the life of the bulbs.
