No I just bought a wiring harness, I also grounded the head unit to the wiring harness in stead of to the body of the car. Could that have something to do with it?

It's possible. Check the bulb first though in case it's coincidence.

I agree, check the bulb first, or just buy a replacement and try it.
If the bulb checks out OK or the replacement doesn't work, disconnect the head unit (unplug it at the harness connector) and see what happens.
Also, check your fuses in the fuse box.

The radiator fans & a/c compressor stopped working the other day. The fuses, relays and grounds all check out. There is no loss of freon. When you select a/c on the control-head, the indicator lights but compressor does not engage. The radiator cooling fans do not come on at all. The engine almost overheated in rush-hour traffic. I can't drive this car until I resolve the cooling issue. Does anyone have any ideas?

which fuse block are you looking at? The ones controlling your problems are underhood, not in the passenger compartment. There's a 10 amp marked "37" that controls the AC compressor AND the Body Control Manual---so that's one suspect.

The fuses that I checked were the ones under the hood. I suspect the BCM is faulty because the Theft System indicator has been on constantly for the past year. Do you have any idea how much a BCM will cost to replace? I need to get this car back on the road.

Well the retail on the part is about $250 bucks, with a little bit of labor to R&R, and then it has to be programmed properly with the scan tool.
#1118 of 1159 2003 Pontiac Grand Prix GT Can anyone help me with the following problems?
May 24, 2012 (8:29 am)
Approximately six months ago, I noticed that once my car started and the running lights were on, when I turned on the heater or defroster inside the car the running lights would go off. If I shut off the heater the lights came back on. This went on for the past 4 months until finally the defroster, heater, fan,the front seat heater, and air-conditioner don't work, the interior clock does not display the time and I have been reading the forum posted here on the Grand Prix problems. Has anyone reached a reason for these issues? I need to get it fixed, but I don't want to spend a fortune for a local mechanic to try this and that. The car runs well otherwise, can anyone help me and let me know what the best fix for this problem is?
