I removed control panel on the drivers door with the switches for locks and windows. took it in the house thinking that there was maybe a condensation/corrosion problem. first thing I did was put the wives hair dryer on it and after a few seconds heard a couple of clicks which I think where stuck internal buttons underneath the push/pull switches. went and hooked it up, perfect no problem.
Prior to this I tried everything, resetting, unhooking battery, fuses, unplugging/plugging back in, checked wires in door jam, the only thing I didn't get to was the the transmission shifter switch which was next on the list.
hope this works for someone. nb put the hair dryer on the hottest setting
