Volkswagen Jetta Headlight Adjust Screw
Simple Ways to Troubleshoot a Faulty Volkswagen Jetta Headlight Adjustment Screw
The headlight adjustment screw holds the headlights in position to give you a good view of what's ahead of your vehicle while driving at night. But when this screw fails or break, it may change the orientation of your headlights and affect your visibility. This is the reason why knowing the problems associated to your Volkswagen Jetta headlight adjustment screw and knowing the ways to troubleshoot them are advised. Here are some tips to help you out:
The headlights on your Jetta can get misaligned and point toward different directions. While this won't affect the performance of your car, it can reduce visibility at night and cause a road accident. Depending on the situation, either of your headlights may point to the sides or to the ground, much lower than the normal level for headlights. This high-risk problem should be fixed immediately to avoid unwanted consequences. Adjusting the headlight adjustment screw is easy and should only take you about 15 minutes. All you need to do is to gently turn the screw using appropriate tools like flat-head and Phillips-head screwdrivers depending on your car. Flash the aligned headlight to a wall and mark where the other headlight should level with.
Broken or unthreaded screw
The headlight adjustment screw on each of your headlight assemblies can break or wear out after some time. But this part can also unexpectedly fail if you tighten it too much while adjusting your headlight. Keep in mind that over tightening the screw can cause it to break or to have its threads loose. That's why it's important that you make slow and gentle strokes when using the headlight adjustment screw. If the screw breaks, you can try pulling it out while supporting the headlight assembly with your other hand. Should the threads get stuck, however, shaking the screw until it becomes loose should do the trick.
Screws rust over time, especially if exposed to harmful particles like water, dirt, and salts. Should the headlight adjustment screw begin to rust, replace this right away with a new one to avoid getting it stuck and harder to remove the next time you need to adjust your headlight. But if you're not in the market for a new screw, applying rust remover and using a scouring pad to remove the traces of rust can solve this problem.
