Thanks for the reply,
when I open any other door, there are no interior lights. When I put the keys in the ignition with the door open there is no chime, unless I wiggle the key around, I dont think that those things are related, but just incase.
I checked in my chilton manual and found that both the windows and interior lights get their power from the g.e.m. on that circuit. I hope thats not the problem but it looks like it.
Also, I disconected the positive side of the battery for over 12 hours to see if the computer would reset itself, always try the easiest stuff first, but there was no change.
If it is the g.e.m., is that a real pain in the neck to replace? Can you buy a scanner to down load the program to for under $200?
Is it true that the dash in these trucks is set up to hinge down so you can access whats underneath them from the top so you dont have to remove the whole dash? A guy I work with told me that, but I dont know how he knows....
Thanks for your help
