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.
