GMC Repair: 2000-silverado, fog lamps, daytime running lights

Question
I took my truck in for a safety, and they said the daytime running lights didn't work. (they did when I brought it in) also the fog lamps are not working at all. I checked the relay(good), the relay for the fog lamps (good) also fuses are good. The comment I got was maybe now I have a wiring problem?

Answer
Hi
As for the fog lights, check the bulbs first, make sure they did not get water in with the bulbs.
You can also check the bulbs for the DRL's also. The GMC's had a BAD problem with the DRL bulb SOCKETS burning out, hence shorting the bulbs.
Neither system has anything in common with each other that would not affect another system, meaning I do not believe you have serious electrical problems. Granted I do not have the truck here to look at.
I would check all bulbs and sockets.
If already done, please do not hesitste to follow up and I'll do what I can to help you.
Good Luck.
