My foglights do not work and im pretty sure its not the bulbs. Ive tried turning the fogs on whille the daytime lights are on and also tried the fogs when the headlights are on and no luck. Any suggestions on how to fix? Bad foglight switch?

 

The car is a 91 S5 btw, and how would i tell if the fog lights are burnt by inspection?

 

check the bulbs - if you've already replaced them, it might just be wiring or a swtich.

 

I've had my fogs go off twice on my old FC. Both times it was the switch.
