I added H7 HID kit to my 2001 es300. Today, the left side nothing worked. I tried switching both the bulb and ballast with an extra set i had and absolutely nothing. I also checked the fuse and it was ok, is there anything else? I just had a car wash but i have car washed 4 times a week so i don't think that was the issue. Anyone have any input?

 

Does the stock bulb work? If it does not work on that side, it is most likely the fuse.

 

Sprayed wd-40 on all the contacts, let it dry up and they worked, i guess crud and dirt had just built up?
