I bought a set of depo fog lights for my 97 and when I first installed them, they worked completely fine.

Just a couple weeks ago, I go out to my car late at night to go somewhere, start it, turn my lights on, and notice that my foglights didn't come on. So here I am, trying to figure out wtf the problem could be.

I've checked the bulbs, relay, fuse, wiring, and 1 ground. I didn't check the ground up front because I have to take the bumper off to do so. The light on the switch inside comes on, just the lights won't turn on. I'm probably going to check the front ground this weekend, but if that's fine, what else could be the problem? Any ideas would be greatly appreciated.

Thanks in advance guys.

 

My vote: relay

Same thing happened to me, the relay even switched over.

Swapped the relay out with a known working one = works
