Have you checked all your fuses under the hood and the side fuse panel on the dash? I would think the Pontiac's should be the same as the Camaro. If not, you should check under the top fuse panel on the fuse block under the hood. Mine has a horn and foglamp next to e/o. They are the medium size fuses, gray, and have "Omron 8567" written on them w/ other #'s too. If your horn still works, switch the two fuses and see if your foglamps come on. If they come one, obviously you blew your lamp fuse. If not, check your bulbs. Above the foglamp there are some fuses for your headlights and my fuse box cover has the abb. "DR" after them. Not sure, but it might mean "daytime running" probably wrong here though. On the side of the dash in your fusebox, there are some little fuses. I would check your turn signal #2, and power accessory #7(although I don't see why this one would cause it) I know I blew it out trying to install my sequentials the other day, though.

Some weird **** happened when that went out. Anyway, if all that doesn't work, take the time to check out all the other fuses for the hell of it. I hope the Firebirds are similar to the Camaro's or this won't help you much at all. Lastly, keep the damn pressure washer away from your electrical system!

It's best to lightly spray down your engine parts, but keep the water away from your computer, and fuse box areas. Hope that helps. Good luck
