I have a 2008 tC and I cannot figure out what is wrong with the fog lights. They are factory... any suggestions of what I should try?

 

With out a story or symptoms I'm not sure how we're supposed to help. If they're not turning on, then it's an electrical problem. It could be a fuse, the relay, or a loose connection.

 

well.. when I push the fog light button nothing happens.. bulbs are good.. fuses are good.. connections are good..

 

How about adding what you have done so far to ensure all this is good? Did you check power and grounds to the bulbs? My guess is that if you have checked all these, the ground that is for the fog lights is disconnected from the chassis...

 

May sound simple, but are your high beams on? Fogs only work work with low beams - if your headlight switch is on high beam, the fogs won't come on. Make sure they are on low, then try the fogs.
If that's not it, then you'll need to keep checking....
