GMC Envoy Tail Lights

Diagnosing Problems on the GMC Envoy Tail Lights

Tail lights are among the most effective safety feature of a vehicle. They work as a warning device for other drivers on the road to know when you are trying to overtake another vehicle or make a corner turn. When your tail lights get damaged, however, it becomes difficult for you to send signals to other driver. This increases the chances of figuring in road mishaps and accidents. This is why it is very important that you know when your tail lights are acting up. Here are some effective ways to diagnose problems on your GMC Envoy tail lights:

Brake pedal assessment

If you are suspecting problems on your tail lights, the brake pedal is one of the first few things that you need to check. This is because your Envoy's tail lights are directly connected to the brake pedals, and are expected to light up each time you step on the brakes. You can ask for the assistance of another person when doing this. When you step on the brake pedal, the other person should check if the tail lights do light up. If they do, then the problem must be caused by other components on the assembly.

Fuse box inspection

Once you are sure that there is nothing wrong with the connection of your tail lights to the brake pedal, you need to inspect the fuse box in case there are wiring problems. The wires serve as passageway for electricity to be transferred from the generator all the way to your tail light assembly. So if there is a faulty wiring connection in the fuse box, it won't be possible for the tail lights to function accordingly. Locate the fuse box and inspect whether the tail light fuse is blown or not.

Tail light housing check

Another component that you have to inspect is your tail light housing. Sometimes, tail light problems are not caused by internal issues on the assembly. It could also be that the housing is busted, thereby causing damage on the wirings. When the wires of your tail lights are exposed, they tend to malfunction after some time. In order to avoid this kind of problem, make sure that your tail light housing is in good shape.

  • Proper Way to Preserve Your GMC Envoy Tail Lights 27 February 2013

    Tail lights play an important function in your vehicle. Also known as tail lamps, they work as a signaling device to let other drivers know of your intention to make a turn. At the same time, they are also used to light up the rear area of the vehicle when you are on reverse gear. Unfortunately, the tail lights are also bound to get defective after a couple of years. And when this happens, it is imperative that you get a replacement right away so as to avoid safety issues and problems with the law. Here's what you can do to prolong the life of your tail lights:


    Clean the lights often.

    In any maintenance procedure, having a regular cleaning session is imperative. This is because thorough cleaning can effectively prevent the accumulation of dirt and dust that can greatly affect the function of the tail lights. Cleaning your tail lights should be done on a regular basis, so make sure that you follow your schedule. Also, see to it that you are only using the proper cleaning materials such as cleaning solution and soft cloth or sponge.


    Remove moisture on the lens.

    Moisture is another common tail light issue that needs to be addressed. In order to provide you with ample lighting, the lens of your tail light housing should also be free of moisture because it tends to make the light less bright. If you want to make the most out of your tail lights, make sure that there is no condensation on the lenses. You can do this by carefully taking out the tail light housing and wiping the moisture off.


    Assess the tail light assembly's condition every now and then.

    It is also very important for you to check on the condition of your tail light assembly every once in a while. This way, you get to see if there are problems on the assembly that need to be fixed at the soonest time possible. There is no need to do this often, though. You can assess your tail lights at least once every month for quick fixes. Visual inspection can also do the job, but if you want a thorough inspection, you can always get the services of an expert mechanic.
