Common Problems with the Mercury Grand Marquis Headlights
Driving safely through any low-light road conditions is a must. With your Mercury Grand Marquis headlights, you are guaranteed with a clear road ahead, especially at night. Due to their location on your vehicle, headlights are made from the most durable materials to make sure that they are working properly. Headlights are built to last your car's lifetime, but they are prone to damage. From front-end collisions to busted bulbs, these are some of the most common reasons why headlights get damaged. If you encounter these problems, it's time to perform some troubleshooting. Below are some of the most common headlight problems encountered by Mercury Grand Marquis owners and some tips on how to troubleshoot them:
Moisture or fogging
Fogging or moisture buildup inside the headlights is one of the most common problems encountered by vehicle owners. Since car manufacturers have switched from glass to plastic lenses, headlights became prone to fogging overtime. Plastic lenses, although durable, are prone to severe weathering. They can develop small cracks that let moisture seep into the headlights. Dirt particles can also enter the headlight enclosure and affect the bulb's illumination. Your car's headlight lens can be replaced, and there are a lot of lens repair kits available in the market today.
Flickering or decreasing illumination
Another common issue affecting your car's headlights is either decreasing illumination or flickering. Dirt, discoloration, and moisture can affect your headlights' illumination. Flickering headlights, on the other hand, can be caused by faulty wiring or loose light bulbs. Decreased headlight illumination can be resolved by the making sure that your car's headlights is clean at all times. Inspect the headlights' lenses for any sign of damage or discoloration. Replace the lenses when needed. For flickering headlights, check the wirings and make sure that there are no loose or faulty wirings. Remove damaged wires and replace them with new ones.
Dimming or non-working headlights
Non-working or dimming headlights can be caused by a busted fuse or grounded relay. Check your car owner's manual for the location of the fuse box. Use a voltmeter to check if the fuses are working. Also, inspect your headlight's relays and switches for stripping or damage. Replace busted fuses, stripped or damaged relays, and switches to resolve the issue.
