Hello,

The driver side headlight is not working. The headlight appears to have some sort of discoloration or residue on the connector. There manual only shows fuse diagrams for halogen bulbs. I have HID/Xenon bulbs. I don't know if it's a fuse or relay issue. However, there appears to be damage to the wiring that connects to the bulb itself (the aforementioned discoloration or residue on the connector).

Can you help me locate the fuse or relay so I may check them?

If it is the wiring within the assembly, is it possible to replace that? If not, is there a way to bypass that wiring to replace it? Only the wiring within the assembly seems to have an issue.

Thank you!

Hi:
If you are seeing a discoloration and corrosion, chances are the socket is bad due to heat. Are you able to take a pic of it for me to see?

This vehicle also has ballast which produce high voltage. You need to be careful when working on it.

Next, if both high and low beam stopped at the same time, check and confirm the ground is still good. See pic 1 for location.

As far as a fuse or relay, there is a high relay, but that wouldn't affect the low beam. Also, there isn't one fuse for both high and low beam.

Make sure the bulb is good and check the ground. Also, if possible, upload a pic of the damaged item you mentioned.

Take care,
Joe
