Is there a fuse or relay or something for the stock bumper mounted driving/fog lights? If there is, where is it?
Mine don't work anymore. I flip the switch back and forth and nothing.

 

I dont have the factory fog lights but my guess is that the fuse blew. I know of two fuse boxes, one in the engine bay and one in the passenger compartment under the glove box on the wall to the right. Check your manual for what fuse it is and see if it is blown. If not, im not sure what might of happened. Maybe your switch was disconnected..? I've been behind that switch panel and although I dont have the fog switch, the other switches (defroster, rear wiper) are very secure but its worth a look. Hope I helped! also its possible one bulb blew a while ago and you didnt notice until they both didnt work. Check your bulbs. -Rob

 

Check both relays in fuse box under the hood and the blue 15amp fuse closest to passenger side fender too .... Both in fuse/relay box under the hood

 

Mines an 89 there's four underhood relays, I can't find the fuse, any idea. Sorry for jacking
