Why won’t my caravan lights work?

If any caravan/trailer lights are not working, then the first thing to check is that the trailer plug and socket are properly connected. That might sound like a simple thing but it’s a good place to start. Correctly functioning trailer lights rely on an earth return to the negative of the battery.

Why are my camper tail lights not working?

If all trailer running lights are out, and the tail lights do not light up, the issue is probably not bad bulbs. To rule out the simplest solution, however, check the trailer tail light bulbs and replace if they appear burnt out. Next, ensure that your trailer cord is seated firmly in the socket.

How do you diagnose tail light problems?

Once the fuse that controls your tail lights is identified, it can be tested using a fuse tester, which will light up if the fuse is good. If it doesn’t light up, the fuse should be replaced with one of the same size and amperage. On certain fuses, you can visually see a break in the metal wire inside a bad fuse.

What fuse controls the tail lights?

The tail light fuse may be located in either the fuse panel in the front passenger side of your vehicle or in the main fuse box under the hood. Once you’ve opened either the panel or the main fuse box, locate the tail light fuse. If you’re unsure which one it is, use the owner’s manual for guidance.

How do you check a tail light fuse?

On most newer cars it can be located under the hood or the dash. The manual will have a labeled picture of the fuse box showing which fuse is which. Making sure the ignition is off, take the cover off of the fuse box and locate the taillight fuse. Use a flashlight to inspect the fuse and determine whether it’s blown.

How do you check tail lights?

To test your brake lights and tail lights, get in your vehicle and turn on the ignition switch. You do not have to actually crank your engine. First, check your tail lights by turning on your headlights. If working properly, they will come on simultaneously and glow red.

6 Common Causes for Tail Lights Not Working But Brake Lights Are

When dealing with an electrical component that isn’t working properly, especially when it comes to faulty tail lights, the first thing to check is the fuse. In its most basic form, a fuse consists of a metal band enclosed in a plastic container that is designed to rupture when the current flowing through it becomes excessive. As a result, other sections of the electrical system are kept from being destroyed as well. Typically, there are two spots in an automobile where fuses may be found.

  • When dealing with an electrical component that isn’t working properly, especially when it comes to faulty tail lights, the first thing to check is the fuse in the component. A fuse is essentially a metal band enclosed in a plastic container that is designed to rupture when the current running through it gets excessive. It is used to protect electronic equipment. Another benefit is that it prevents harm to other components of the electrical system. In most automobiles, fuses are located in one of two locations.

Each fuse is in charge of a distinct electrical component, and the functions of each fuse should be indicated on the cover that you removed in order to have access to the fuses. If not, they can be recognized by consulting the owner’s handbook or by searching online for a schematic that corresponds to the year, make, and model. Once the fuse that controls your tail lights has been located, it may be examined with a fuse tester, which will illuminate if the fuse is in good working order. If the fuse does not light up, it should be replaced with one that has the same size and amperage as the original.

2 – Bad Tail Light Bulbs

If the fuses beneath the hood and within the cab are found to be in good working order, the next suspect to investigate is the tail light bulbs themselves. It’s usually necessary to remove the tail light cover, however some vehicles have an access panel that allows you to reach in and twist the bulb out of the lens without removing the cover. The most accurate approach to determine if a bulb is faulty is to remove it from the socket it is currently connected into and carefully check the filament.

It is necessary to replace a broken filament with a new bulb if the filament is no longer illuminated. What if you’ve already replaced the light bulb with a new one and the problem persists? Please continue reading. Related: 5 Reasons Why Your Turn Signal Is Blinking Too Quickly

3 – Socket Failure

It is possible for the socket into which the bulb is inserted to malfunction. Typically, corrosion is the source of this, which is brought on by moisture entering the plug socket. However, it is possible that it will fail as a result of a faulty connection of the wires in the rear. If the bulb and fuse both appear to be in excellent working order, you should inspect the condition of the socket while the bulb is removed. Examine the pins for any discolouration, such as white, blue, or brown, as well as bent or broken pins.

No energy reaching the pins indicates that there is a problem further up the electrical cable.

4 – Worn Out Wiring

The most likely cause of a lack of electrical power flowing into the socket, after all fuses have been examined and found to be in excellent working order, is a damaged or broken wire somewhere along the line. This is the stage at which you’ll need to get a wiring schematic and visually examine the wires running through the tail light circuit for broken wires or cracked insulation, among other things. Check the body grounds that are coming off of this circuit as well. Additionally, a filthy, loose, or damaged ground wire will result in an interruption in the flow of power to the sockets.

5 – Control Switch Failure

Another reason for the failure of the tail lights to illuminate is a problem with the switch that controls them. The headlight switch on the dashboard might also fail, and it should be examined if everything else has been tested and found to be in working order. Under normal circumstances, this switch activates the headlights, taillights, and parking lights. The possibility that this switch has failed exists if all other components of the tail light circuit are in proper operating condition. This may be removed from the dashboard and tested with a multimeter to determine whether or not it has failed.

6 – Dirty or Bad Ambient Light Sensor

A sensor for ambient light is also found on the dashboard of many contemporary automobiles. This enables the vehicle’s computer to automatically turn on and off the headlights and tail lights based on how bright or dim the outside light is at any given time. Some people also choose to switch off the daytime running lights on their modern automobiles. If your parking lights and headlights do not illuminate, but your brake lights do, this is most likely the source of the problem. If this sensor becomes faulty or becomes too dusty, it will be unable to determine whether it is day or night outside and will thus fail to switch on the lights.

Conclusion

Overall, tracing out an electrical breakdown may be a difficult and irritating task to say the least. Fortunately, tail light bulbs are often operated on their own separate circuit, making it quite simple to identify and resolve problems. All of these failures will result in the inability to operate the tail lights, but they will not prevent the brake lights from turning on when the pedal is depressed since the brake lights operate on a separate line of circuitry.

When a driver notices that their tail lights are not working, they should rectify the issue as soon as possible to ensure their own safety and the protection of others.

Tail Lights Not Working But Brake Lights Are: Fixed (Answer)

Taillights are extremely important in maintaining a safe driving distance, especially at night. You may, on the other hand, discover that your tail lights are not functioning, although your brake lights are. Despite the fact that your brake lights are completely operational, other cars travelling behind you may not be aware of your presence. It is possible that an accident will occur as a result of malfunctioning tail lights. Tail lights and brake lights that are not working might be caused by a variety of factors.

Reasons Why This Can Happen

In your car’s taillights, light bulbs are used, which function in a similar way to the light bulbs in your home. As a result, much like your household bulbs, your tail lights are susceptible to being burned. Furthermore, the brake lights and tail lights on your automobile require various types of light bulbs. As a result, the taillight bulb may become damaged while the brake lights are unaffected. The outcome is that your brake lights will operate, but your tail lights will not work as a result of this.

2. Dislocated or Damaged Wiring

Tail lights can be rendered inoperable by damaged or interrupted wiring, whereas brake lights are unaffected. Because each bulb has its own power supply, the wiring for the two lighting fixtures is distinct. A recent collision that occurred in the rear of your vehicle might enhance the probability of this problem occurring. As a result, if the cables connecting the breaking lights are not destroyed, the lights may be operational. This problem happens when there is a severe or complete failure of the power wires.

3. Blown-out Fuse

Similarly, a blown fuse might be another reason for the inability of the tail lights and brake lights to function properly. Each electronic component in your vehicle is connected to its wick. As a result, when a certain fuse breaks, the light associated with it stops operating. This functionality explains why taillights may fail to operate while brake lights continue to function properly. When a fuse blows, it causes the circuit to be turned off. Check your fuse to see if the problem is with your tail lights or with your fuse box itself.

4. Electrical Problems

Another issue that might cause your tail lights to stop operating is an electrical malfunction. In this instance, though, you will need to take your vehicle to a technician. A blown fuse and poor wiring cause a domino effect that results in electrical difficulties, which are common in the home.

How to Check Each Component

You should check a variety of factors in order to determine whether your tail lights are malfunctioning. One of the things to look for is a burned out bulb, which is an easy task to complete. Either the trunk or the lenses can be removed in order to get access to the light. After that, you may unscrew the bulbs and look for any that have been darkened. Additionally, the automobile dashboard contains a signal indication that indicates when a bulb is not functioning properly. You may also use this signal indicator to determine whether or not your bulbs are malfunctioning.

Another method is to check to see if the filament of your light is still intact. The thread on the working bulbs is still intact. If it turns out that your bulbs are the source of the problem, all you have to do is change them. Obtaining car bulbs may be accomplished at a local automotive store.

2. Damaged or dislocated wiring

It is simple to determine the condition of your taillight wiring. To obtain access to the wiring, you must first open the trunk and remove the cover. If the wires are not properly secured, this might be the source of the problem with the tail lights. To correct the situation in this scenario, you just need to reconnect the cable connections. For severed wires, on the other hand, you will need to take them to a technician for appropriate repair.

3. Blown-out fuse

It is possible that a blown fuse can result in your tail lights not working. The automobile fuse appears to be identical to any other fuse on the market. It is necessary to first find the fuse box in order to inspect this component. However, while you are inspecting the fuse box, make sure to turn off the car’s ignition. Making sure that the car’s ignition is turned off may spare you from an electric shock. The use of a flashlight might assist you in identifying the fuse for the tail light. After you’ve determined which fuse to use, you’ll need to remove it and check it.

A broken wire, on the other hand, shows that the wick is defective.

Fuses have a wide range of voltages, therefore you must make sure you are using the correct fuse.

4. Electrical problems

Last but not least, you must investigate the electrical problem. When fuses and wires fail, the most common cause of mechanical failure is the result of the repercussions of the failure. Mechanics, on the other hand, are in a better position to identify and correct such problems.

5. check Wiring

When your tail lights stop working but your brake lights are still working, you should check your wiring. It’s possible that the rats chewed away at the wiring in your car’s interior. As a result, you must double-check that all of the connections are tightly secured together before proceeding. In addition, it is necessary to examine the wiring schematic for accuracy. It will assist you in understanding how your automobile’s lighting system operates and will instruct you on how to make modest adjustments.

  • Corrosion might also be a contributing factor to bad wiring.
  • As a result, dampness can cause rust to form, which can cause the entire electric circuit to malfunction.
  • Checking the wiring also gives you the opportunity to detect a problem with your automobile at an early stage.
  • You will also have a greater understanding of your automobile.

6. Check Turn Signal Switch

In certain automobiles, the switch for the tail lights receives its electricity from a single electrical circuit. This includes the turn signal light as well if the situation calls for it. This function, however, is not available in every automobile. As a result, a wiring diagram should be used to determine whether or not your vehicle runs in this manner. This illustration will assist you in determining whether or not the wires are traveling through the switch signal turn or not. Identifying the cable that links the turn signal switch to the tail lights, on the other hand, is essential.

Following that, your tail lights should normally function properly, resulting in a safer driving experience for you.

As a result, the likelihood of an accident occurring is reduced.

In order to ensure that your car is in excellent working order, it is necessary to inspect it on a regular basis. Additionally, evaluating your automobile allows you to identify any potential problems with it as soon as possible. It also assists you in keeping it in good condition.

Why Do My Brake Lights Work but My Tail Lights Don’t?

Car problems are something that everyone has to deal with at some point in their lives. These issues might range from minor inconveniences to major headaches that can cost you a small fortune in repairs. As a result, it’s important to keep an eye out for problems with your vehicle before they get too serious. You should pay close attention to the headlights and tail lights of your vehicle. Many of you may be perplexed as to why my brake lights are operational yet my tail lights are not. If you happen to be one of them, then this is precisely what you need to be reading at this time.

Why Do My Brake Lights Work but My Tail Lights Don’t

Why do my brake lights work but my tail lights do not? In this section, we’ll go over the most likely explanations for this.

Faulty Tail Light Bulb

One of the most common reasons why you could notice your brake lights functioning while your tail lights are not is that the bulbs put in the tail lights were broken when you purchased the vehicle. You need conduct some tests to determine whether or not the bulbs are the primary cause of the problem, and in order to do so, you will need to remove the tail light cover. It is not a tough task that you have before you. It is necessary to ensure that the filament in the bulb is operational. If you observe illumination, it means that the system is operational and that something else is causing the problem.

As a result, replace the bulbs.

If you don’t know how to do it, there are numerous simple step-by-step tutorials and instructional videos accessible. The majority of them will assist you in achieving your desired result. You’ll need to explore a bit harder for other possible causes if the tail lights are still not functioning.

Problematic Fuse

More than just the broken bulbs, you will notice that there is something wrong with the fuse, which is responsible for ensuring that the entire electric system of the automobile operates smoothly and without causing any harm. Its primary function is to trip when the current flow becomes excessive. The electric system is safeguarded by this rupture. Now, if you want to check the fuse, there are two locations you may look in the automobile to find it. The first is the fuse box. The first one may be found on the panel located in the cabin of the vehicle.

  1. The second location is directly beneath the hood of the vehicle.
  2. All that is required is that you determine which fuse is blown.
  3. When the lid is removed, it is possible to access the fuse.
  4. This is something that you should be able to discover in the owner’s handbook or on the internet if you search for it.
  5. Whether or not it works may be determined by checking whether or not the tester is illuminated.
  6. If, on the other hand, it does not illuminate, you will have to get a new one.

Bad Bulb Socket

If you have already tested the fuse and the bulbs, and you have determined that they are both in perfect working order, the next item you should check is the socket. Sometimes a problem with the socket might result in the tail lights not operating properly. Moist conditions have the potential to cause harm to the sockets. Building up of any form of moisture can cause problems with the wiring, which can eventually result in failure of the circuitry. It is also possible that the sockets will not function correctly due to a faulty connection of the wiring.

You should either update it or get it checked out if this is the case for you.

So keep an eye out for any of these evident issues so that you can address them as soon as possible.

Well Worn Wiring

The electrical system is responsible for ensuring that everything runs smoothly. And if there’s a stray wire out of position, there’s a good probability. You won’t be able to proceed with this unless you have a suitable wiring diagram for the automobile. And you’ll have to track down the ones that are linked to the tail lights in order to figure out what’s going on with them.

Googling around for a problem with the tail light is just too time-consuming and needless in this situation. As well as paying attention to a worn-out wire in the automobile, you should also pay attention to the ground circuit, which can occasionally cause an issue with the tail lights.

Faulty Light Sensor

Automobiles are becoming more equipped with automated functions as time goes on. This makes driving a whole lot less difficult for us. It has a light sensor, which is one of the novel features. In many cases, the computerized system of the automobile can determine when to turn on which light and when not to. If there is a problem with the sensor, it is possible that this is the cause of your tail lights not working. Even if the sensor may be programmed to turn off the lights during the day, it may be unable to distinguish between day and night due to malfunctioning.

It is possible that the sensor will become faulty, in which case you will need to have it repaired or replaced with a jeep light bar.

In that situation, a thorough cleaning will be sufficient.

Failure in the Control Switch

As time goes on, automobiles are becoming more and more equipped with automated functions. For us, this makes driving a whole lot less challenging. It has a light sensor, which is one of the new additions. Most of the time, a car’s electronic system can determine when to turn on particular lights and when not to.

5 Reasons Why Brake Lights Not Working But Tail Lights Are

You and other drivers on the road are at risk if you are driving at night with either your brake lights or your tail lights not functioning properly. It takes a long time to notice when the brake lights are not functioning but the tail lights are, or vice versa, because they are so close together. This is due to the fact that you will not be aware of what is going on in the backseat unless someone calls your attention to it. For road safety, both the brake and tail lights are essential components.

It has the potential to cause serious accidents, particularly on dark roadways or during periods of heavy rain or snow.

The Reasons for Brake Lights Not Working but Tail Lights Are

While driving at night with either your brake lights or your tail lights not functioning, it is extremely dangerous for you and other cars on the road. When the brake lights are not working but the tail lights are, it takes a long time for the driver to realize. As a result, until someone points it out, you will be completely unaware of what is going on in the backseat of your car during the drive. Road safety necessitates the use of braking and tail lights. The other cars behind you will not be able to tell if you are moving or not if any of these devices are not functioning properly.

Especially on dark routes or during heavy rain and snow, it has the potential to cause catastrophic accidents. In addition, if the police observe you driving without working lights, they will issue a citation for you.

The Light Bulbs

The most common reason for brake lights not functioning but tail lights operating is a blown light bulb, which occurs more frequently in older vehicles. Remove the screws from the bulb lens using a screwdriver (which you can access through the trunk or see your vehicle repair manual to get the exact location). To remove the bulbs from the socket, push them down and spin them counterclockwise. It’s possible that the cause is blown out lights. If your bulbs have been discolored or if the filaments have become brittle, you should replace them.

In most European automobiles, the same bulb is used for both the taillights and the brake lights.

Fuse Box and Light Switch

You’ll need to locate the fuse box or the power distribution center to complete the task (PDC). The fuse panel will be located beneath the dashboard, while the PDC will be located under the hood. The brake light switch may also be discovered under the dashboard, and it should be checked to see if its plunger is in contact with the brake pedal arm. The brake lights will be affected if there is an issue with the fuse box or light switch. If a fuse has blown, it should be replaced with a brand new one.

Apart from that, you should try to determine what caused the blown fuse.

The Electrical Ground

You’ll need to locate the fuse box or the power distribution center to complete your mission (PDC). Located beneath the dashboard is a fuse panel, and under the hood is a power distribution center (PDC). It is also possible to find the brake light switch under the dashboard, and it should be checked to see if its plunger hits the brake pedal arm. The brake lights will be affected if there is an issue with the fuse box or switch. The fuse should be replaced in the event that it has blown. Please keep in mind that the replacement unit must have the same ampacity as the previous one.

Other than that, it is likely to become a reoccurring issue.

Additionally, attempt to determine the source of the blown fuse. Aside from that, it will be a reoccurring issue.

Check the Wiring

If all of the above-mentioned components are functioning properly, you will need to explore elsewhere for the root of the problem. It is possible that the wire from the fuse panel to the brake light switch, as well as the cabling from the switch to the bulb sockets and lights, is loose or fraying. It is possible that the connector and bulb housing have become rusted. If you discover a problem with these components, you must replace them.

Examine the Turn Signal Switch

In some car types, the brake light circuit can be found as a component of the turn signal circuit. If the brake light switch is broken or malfunctioning, the brake light will not illuminate. Examine the wiring schematic for the switch and look for the single wire that connects the brake light and turn signal switches to each other.

Connect a test light to the electrical connector on the turn light switch, activate the brake light switch by squeezing the brake pedal, and then back probe the wire with the test light. If the test light does not come on, you will need to replace this wire.

Why Won’t My Tail Lights Work When My Headlights Are On

It is possible that the tail lights will not function correctly but the brake lights will function properly. The connectors for the rear lights and the headlights are separate. As a result, one set will continue to function normally, while the other set may encounter difficulties and cease to function. Tail lights can be turned off for a variety of reasons, many of which are almost identical to the reasons why brake lights are not working but tail lights are. The following are the causes of malfunctioning rear lights:

  • Electrical problems include: blown fuses, damaged wiring, and burned out bulbs.

It is recommended that you take your car to an experienced technician if you are still unable to determine the source of the problem with your non-functional brake lights or tail lights or if you are unsure about the measures outlined above.

Trailer Lights Not Working Solution: Check the trailer light wiring ground

Clean the ground contact and secure the ground wire to the metal frame using a ratchet or wrench. After that, inspect the ground wire. The majority of issues arise in this area. Remove the ground screw and use sandpaper to smooth up the wire terminal and trailer chassis contact points. If the ground screw itself has become corroded, it should be replaced with a new one.

Trailer Lights Not Working Solution: Replace bad bulbs

Using a wire brush, clean and retighten the ground contact on the metal frame. After that, look for a ground cable. The majority of issues arise at this location. Disassemble and sand the wire termination and the trailer chassis contact with sandpaper after removing the ground screw. The ground screw itself should be replaced if it has been rusted beyond repair. Upgrades to a Utility TrailerStep Four

Trailer Lights Not Working Solution: Clean corroded sockets

Fine sandpaper and a 3/8-inch dowel can be used to remove rust from hard-to-reach places. If the light continues to not operate, it is possible that corrosion has formed in the socket at the contact points. Hot glue a piece of 220-grit sandpaper to the butt end of a 3/8-in.dowel to the butt end of the dowel. By spinning the dowel and moving it from side to side, you may clean the contact points. Insert the bulb after putting a dab of dielectric grease (purchased from a hardware shop) on the contacts.

You should wipe away any rust with sandpaper and check the lights once more if you find any. Step 6: Discover the 20 ingenious camping gear items available at Harbor Freight.

To check for a broken wire, first determine the color of the wire that connects to the socket, and then locate that wire on the connector in front of the socket. Connect one end of a long jumper wire (Photo 2) to a connector pin, and then connect the other end to the continuity tester to complete the circuit.

If the light does not come on, trace the wire and inspect it for bare patches or breakage, if necessary.

Trailer Lights Not Working Solution: Replace the trailer light wiring

If the wiring system is severely corroded, don’t be afraid to replace the complete system. If everything else fails and you discover that the wiring harness has been severely corroded, you may purchase a new wire harness for around $20. A new harness comes with everything you need, including the connector, lights, and lenses, as well as detailed instructions. Typically, it takes around two hours to complete the installation.

Tail Lights Not Working But Brake Lights Are? (How To Fix)

The longer you have had your car, the more probable it is that you may experience electrical difficulties at some point during that time. While most of the time, such issues are as simple as burned bulbs and blown fuses, there are times when they may get a little more involved. Don’t be anxious; even if you’re stressed out and concerned about the cost of repairs, the answer is generally less complicated than you anticipate it would be. Here are the most typical reasons why your taillights are not working, yet your brake lights are still working, as shown below.

Additionally, a blown fuse, faulty wiring, or corrosion in the sockets or plugs might create this problem.

Control light switch failure might possibly be the source of the problem. While not all of the probable reasons are included below, they are the most often seen. Here’s a more in-depth look at the most common reasons why taillights don’t work yet brake lights do in situations like these.

6 Taillights Don’t Work But Brake Lights Do Causes

Brake lights are commonly equipped with a twin filament bulb, and it is possible for just one of the filaments to become damaged or broken. When this occurs, one side of the bulb, such as the brake light, will operate properly, but the other side, such as the taillight, will not. Furthermore, several automakers utilize different bulbs for the taillights and the brake lights on their vehicles. The taillight bulb will need to be replaced if it becomes damaged or burnt out. After everything is said and done, it’s possible that you’re utilizing the wrong bulbs if you’ve only recently changed them.

That is not correct.

In the event that you’ve already disposed of your old bulbs, consult your owner’s handbook or Google to see if you can locate the suitable bulb for your car!

2. Blown Fuses

The most likely cause of your vehicle’s taillight failure is a blown taillight fuse, which may be identified by the presence of a few burned-out bulbs. Finding your vehicle’s fuse box and checking the fuse with a test light or a multimeter are the only things you need to do to check. It is sufficient to just remove the taillight fuse and examine it if you do not have either. If you’re not sure whether or not the fuse has burned out, try swapping it out with another fuse of the same amperage. If the problem is moving, then the fuse is the source of the problem.

It might be tempting to increase the amperage in order to guarantee that the fuse does not blow again, but doing so can cause worse difficulties if the fuse does not safeguard the system as it should!

3. Faulty Control Switch

Although it is commonly overlooked by do-it-yourself technicians, it is one of the most common causes for your taillights to quit operating. The control switch in the cab of your car informs your taillights when to turn on and off, and if the switch isn’t operating properly, you’ll never be able to turn your taillights on! When this element fails, you will almost always lose the ability to use the front parking lights as well.

4. Wiring Issues/Bad Grounds

Troubleshooting wiring problems are the misery of many a mechanic’s existence. Despite the fact that they might be difficult to debug and determine the specific problem, they continue to appear on sometimes. A typical problem with older automobiles is that the wiring is faulty, the lines are crossed, and the vehicle is corroded beyond repair.

5. Corroded or Damaged Sockets or Plugs

Everything inside your car becomes exposed to the elements if the taillights aren’t securely sealed once they have been installed. While this can result in issues throughout the system, the socket itself is the most vulnerable point. Because they are exposed to the weather, these sockets are susceptible to rusting and corrosion, which can result in a variety of electrical difficulties. When replacing a bulb, it’s important to check the socket to make sure it’s in excellent working order as well as the bulb.

If there is corrosion in the socket, a wire brush and WD-40 should be used to clean it. However, if the damage is severe enough, you’ll have to have the socket replaced entirely.

6. Bad Ambient Daylight Sensor

When it is dark outside, modern automobiles are equipped with automated parking lights. This implies that they will turn off if there is enough light outside to see through them. Although this varies depending on where you live, have you checked to make sure that it is not too bright outside for your tail light to turn on? In other cases, however, it might be caused by a malfunctioning ambient light sensor, which informs the vehicle when it is appropriate to turn on the taillights. A popular location for this sensor is in the front windshield, and it is not very usual for it to fail due to wear.

Tail Light Troubleshooting Guide

The KISS principle must be followed while solving problems. Of course, this is not a literal translation, but you must keep things simple, dumb! It is, in its most basic form, the principle of Occam’s Razor, which states that the simplest answer is generally the issue. Ensure that the lights haven’t burned out and that you are receiving electricity before you begin digging into wire harnesses and verifying grounding points. No power is generally indicative of a blown fuse, although it might also indicate a malfunctioning switch.

  • They are also the most straightforward to debug and repair, which is even better for you!
  • To begin, check for power at the socket, but only with a known good ground as a starting point.
  • If rust or anything else is covering the terminal, you’ll need to clear it off first before proceeding with installation.
  • However, if you’re getting power and there’s no corrosion, the problem is most likely a grounding issue that has to be addressed.
  • It is possible that you have a wiring problem between the socket and the fuse if the fuse is receiving electricity but the socket is not.
  • Once again, if you have power at the switch but not at the fuse, the wiring issue is somewhere in the middle of the system.

Summary

When it comes to electrical gremlins, nothing is more aggravating. The good news is that with a little automotive know-how and a fundamental grasp of electrical principles, there’s no reason you can’t hunt out the source of your malfunctioning lights!

It may seem intimidating at first, but the majority of electrical problems are inexpensive to repair and will not recur if the task is done correctly the first time. Even better for rookie technicians, they are difficulties that can usually be promptly troubleshooted and resolved by the individual.
