Is your car's headlight door starting to show signs of wear and tear? Or maybe you're having problems in opening and closing it. Whatever the case may be, you better take a closer look at this accessory to see what the problem is and fix it as soon as possible. Keep in mind that a faulty door will prevent you from properly using the headlights, which will definitely turn your vehicle into a safety hazard. So before a faulty door opens up a lot of other problems, here are some tips when dealing with common issues:
Problem #1: Flip-up headlight door won't open or close.
Solution: If the door gets stuck in the open or close position, you need to take a closer look and see if grime or pieces of debris are stuck between it and the headlight assembly. If dirt or grime is stuck in between, simply clean it out until the culprit is removed. If the cause seems to be an electric problem, check the fuse and relay that control the door. A blown fuse, worn-out wires, and a busted door motor are common causes, as well as a short circuit. To figure out the source of the short circuit, you'll need a multimeter to test voltage to and from certain parts of the door's electric circuitry. Once you've determined the faulty component that's causing the short circuit, fix or replace it as soon as possible.
Problem #2: Headlight door is warped, cracked, or rusty.
Solution: Metal doors are prone to corrosion while plastic ones can warp after years of exposure. If the rusty patches are small and shallow, you can buff them out and give the door a new paint job. But if the rust can't be buffed out, you'll have to get a new door. As for warped plastic doors or trims, it's best to just replace them. A cracked door, whether it's metal or plastic, is practically begging to be replaced.
Other repair tips:
- When repainting a rusty door, make sure the paint color you choose is an exact match to the color of your car's exterior panels. To ensure you get the right color, bring the old door with you when shopping for a replacement.
- If a headlight door was damaged during a collision, better take a look at the entire headlight assembly to see if the glass, bulb, or any other component was also damaged.
- For an easy and affordable way to jazz up your car's looks, simply replace factory headlamp doors with chrome ones. These replacement parts add extra shine to your car's overall look in just a few hours. And because many high-quality doors are available in budget-friendly prices, you don't have to shell out a huge amount of money for these parts.
- If the headlight door relay is busted, better take a look at the other electric components that control the actual lighting assembly since in some models, these electronic parts are designed to work together.
