Common Issues behind Nissan Altima Headlight Assembly Defects
Placed at the front of your Nissan Altima, the auto's headlight assembly is engineered not only for optimum lighting but also for improved resilience to external elements and extreme weather conditions. However, constant exposure to these unwanted elements can take its toll on the auto's headlights. This could soon cause all sorts of lighting and safety issues to your vehicle. If you think you have a faulty headlight assembly, then you had better perform some troubleshooting. Listed below are some common issues that are encountered with Nissan Altima headlight assemblies.
A possible reason behind flickering headlights is a failing charging system, or it could also be a faulty headlight assembly. You can easily diagnose this by taking a look at your car's fuse panel, which is located under the steering column. You see, frayed or damaged wirings may cause the headlights to flicker. Alternately, you can check the hood for damaged wiring that runs to the headlights. If this is not the case, then you may proceed to check the tension on the alternator belt. A defect in the alternator belt causes the car to run low in RPMs, which then causes the headlights to waver.
Yellow or cloudy headlights
If you have been recently experiencing a sudden decrease in the headlight's brilliance, but your lamps have just been recently replaced, then check the headlight cover for indications of fogging or moisture. This lamp defect is easy to detect because of the change of headlight color. You see, the moisture build up is caused by cracks or sealant loss. When the headlight housings are short of sealant, the condensation settles in and affects the lighting performance of your car. So be sure to check for any sealant issues and cracks when troubleshooting for headlight assembly problems.
Other troubleshooting tips
When replacing or inspecting your car's headlights, be sure to wear rubber gloves. In fact, failing to wear them causes the headlights to wear at an earlier rate. This is because the oil from the skin reacts to the bulbs' lighting system and will eventually increase the rate of the headlight's expiration.
