For months one of my fog lights (they aren't the stock ones) has been burnt out. Last night I got bored and decided to fix it. After I put in the new bulb I flicked the switch on and they worked perfectly. I started driving around and after about 20 minutes of them being on I flipped on my high beams and most of my interior lighting went out (guages, radio, shifter). All my other lights worked and even the little high beam light worked. When I turned off the high beams everything came back. I started flicking the switch on and off and it stopped clicking ...broke it, now its stuck on. I tried hooking up another toggle switch but it didnt work. When I unplug the original switch all the lights go out. Do I need to just order a new switch from GM or could it be more than that? How are the fog lights connected to all that other stuff and what would make them do that?
