What Could These Problems Have In Common?

[craven]

All at once the radiator fans, auto headlights, air conditioner (compressor doesnt kick on at all), and the automatic door locks (when shifting out of park) stopped working. I also cannot program the door locks using the instructions in the owners manual (no chimes or anything). I replaced the BCM but that did not correct the problem. Anyone have any ideas??

Thanks!

sounds like one of the relays took a poop....take it and put it on a diagnostics machine, good luck

Yeah the door unlock problem is usually a failing relay. But If all of these things are failing at once It can sometimes be caused by Junk in the fuse box.

Check your fuse box on your drivers side, AND Passengers side for any kind of rust or corrosion. Maybe take out a few fuses and see if they are blown. Make sure to look at them very closely.

If you do see alot of white substance, or rust That will definately cause the problem.
