Default Fog Lights not working

Well couple weeks ago I was trying to fix my power mirror switch and in the process of looking for a broken wire, something shorted out and blue a fuse for my locks and power windows and mirrors and it drained my battery, anyways I recharged the battery and replaced the fuse and everything was working exactly as they were before, except the fog lights?? So I just got around to checking the fuses the other day, and there was only 1 fuse I could find and it was under the hood, and it was still good. so whats the problem?? is there another fuse somewhere? or?

Thanks, Zach

Woah brotha'.....that's a head scratcher. Right off the cuff, the only thing I can think to try is take it back to your dealership and have them Re-Flash the BCM again. It could be that the short caused an overcurrent and it's possible that, it could have spazz'd your BCM, causing it to not recognize that you are Fog Lamp equipped. I've seen stranger ****, but....this one is pretty boggling. Anywho....that's what I'd try first.

Awhile back my fogs quit working too, and I tracked the problem down to the headlight switch. Replaced that and everything started working again. If you have a buddy that you can swap switches with try that and see if it helps.

Any Idea how much it would cost to reflash it?
