Pontiac Grand Am Headlight Assembly

Identifying Problems with Pontiac Grand Am Headlight Assembly

The Pontiac Grand Am headlight assembly serves as your eyes during nighttime driving. When they do not work correctly, it is important to pinpoint the exact cause so that you will be able to provide the exact solution. Also, no matter what the cause of failure is, you need to understand how to do the troubleshooting yourself so you can save on labor costs. Here are simple ways to find the cause of your headlight assembly problem:

When one headlight is not working

The problem might be a bad headlight bulb or an ignitor module. To find out, place the good headlight bulb to the side that is not working. If it works, then you have solved your first case quite easily. But if it does not, take the good ignitor module from the other side and place it on the bad side along with its original bulb. If the bulb lights up, you will need to replace the bad ignitor module.

When both headlights are not working

The problem may lie on a number of reasons, namely, a bad switch, wiring fault, or a blown fuse. Start the inspection by checking the fuse panel first. If the fuse is blown, you will have to replace it with a new one immediately, so you can check what caused it to blow in the first place. If the new fuse blows right away, there is a short or overload that caused it to fail. Check the wiring circuit to find the fault.

If, however, you find the fuse fine, the problem may be caused by the switch. Since switches are very prone to wear and tear, it is normal to have these wear out after several years of service. Simply replace the old switch to get your Pontiac Grand Am headlight assembly to start working again.

But if the problem is not caused by a bad switch, check the wires for any frays and damages. This is very common if you live in rural areas where rodents can easily access the wires and chew on them.

When the headlights don't illuminate the road properly

Check the aim of the headlights-they must be aimed straight ahead. Otherwise, you will be blinding or annoying oncoming drivers as you drive along. Besides this, moisture in the headlight housing can also reduce the useful light.

  • How to Care for Pontiac Grand Am Headlight Assembly

    The most common problems associated with headlights, not just for the Pontiac Grand Am headlight assembly are condensation, scratches, and the yellowing film that diminish light output. Since headlight housings are mostly made of highly-durable plastic material instead of glass, such problems are quite inevitable. To remove all of these, here are a few simple remedies you can do:


    To remove condensation

    If there is any moisture present inside the headlight housing, you can remove it by using a number of methods, all of which requires you to remove the assembly off of the front of your Pontiac. The first method you can use is by simply letting it dry under the sun. Just remove the light bulbs and set the housing in a secure area where the moisture can easily evaporate. Another way is by using a blow dryer, which is quite faster than the other method.


    Once dry, don't rush in putting it right back. Seal all openings up tightly by using a permatex compound or a silicone sealant. This will prevent you from experiencing the same problem over and over.


    To remove scratches

    Since they are always exposed to all types of weather, scratches are not unusual. To remove them, you can purchase a headlight polishing kit from your nearest auto parts store. Make sure you tape the body panels at the edges of the headlight cover to prevent any chemical from getting in contact with the paint. Apply the headlight polish in a circular direction using a microfiber cloth. When the scratches are gone, simply wipe off the polish with a clean cloth.


    To remove oxidation

    As the sun beats down on the plastic headlight lenses, the UV rays break down the plastic material and leave a layer of yellowish, hazy film that can impede useful light. Removing oxidation is quite simple. Just apply some plastic polishing wax onto the headlight covers using your fingers while the lenses are still wet from washing. Then take a sanding sponge and a wet and soapy, 600-grit sandpaper and sand the lenses from side to side. Continue the sanding process with 1200-grit, and then with 2500-grit sandpaper. Be careful to keep the headlights wet at all times. After this, wipe off all excess grit from the surface and apply some polish, letting it haze. Afterwards, buff or wipe it off using a shop towel.
