Fog Lights

Ever since I bought my car my fog lights had not worked. I replaced alot of the fuses and they still dont. Is it possible that I just need to replace the bulbs (is that possible?) or would I have to replace the whole light? Or could it be something else?

Re: Fog Lights

Could be a fuse...relay....switch....bulb....bad wire....connection. The relay might be the easiest to reach, check & determine which direction to go in the circuit to start looking for problems.

Re: Fog Lights

The following may not be helpful at all, but FWIW, from 86-on, Camaro fog lights work with parking lights on and with low beams on. They won't work with high beams.

Oh yeah....Been so long since I "fixed" mine, I forgot about that. Mine stay on even with the High Beams now.

You should change out the bulb, it might be as easy as that, when I got my T/A, neither of the fog lights worked, I changed out the bulbs and that did the trick... they were way over due for getting changed out.

The number you want is 885, however it looks like it not available... you could get the 893. This thread should help...
