Posted this in the wrong thread earlier.

Just recently they went out and are not working at all when they used to fine. I can lock all doors from outside with my key but thats it. None of the power door locks work. When I used to open the door the interior lights would come on and they dont anymore. What could cause this and what should I check?

Bad BCM would cause this. Same problem happened to my 1997. I might happen to have an extra one from the 1993 I had a while back. That is if you don't already have a spare.

Your windows and other electronics still seem to function ok? There is also the bundle of wires (ground?) under the driveside carpet that could be wet/corroded but it sounds like bad BCM. If its only the locks and lights.
