Thanks for replying, 2X95SEs..... I tried resetting the computer (by disconnecting the battery) without success. I was tinkering around with it earlier today & found a brown relay behind the glovebox with the words "power door lock relay" stamped on the side. I couldn't hear it clicking when I pressed the power door switch, so I'm kinda thinking that this may be the cause of the problem....... I'll be looking to get a new one next week sometime.
The only thing that leaves me a little apprehensive is that I substituted the heated rear window relay to try & test it, & that didn't work either--but that relay is a different colour (yellow) & slightly smaller. However, the door lock relay didn't work in the window's slot, either making me think that the 2 relays simply aren't interchangeable. Unfortunately, no other relays will even fit in the slot, so I'll have to take the plunge & try a new one.... fingers crossed! :rolleyes:
