OK... I'm baffled... Here's the situation:

The driver's side door will not lock or unlock with the keyless entry remote control. All other doors/rear hatch work correctly. All doors work correctly with the lock/unlock switch on the door (co-located with the power window switches).

Also, and this is the most interesting part, if I open the door and push in the lamp/security switch to emulate the door being shut the door lock will work. So, I thought the problem might somehow be with the lock/latch assembly (on the side of the door) and I next pushed the latching mechanism closed with a screwdriver to simulate the door being shut. With the lamp/security switch again pushed in (and the door open) It still worked correctly. I tried pushing the latch around into different positions with the screwdriver and still it worked correctly with the door open (and the lamp/security switch pressed in).

I swapped out the lamp/security switch - no luck. I reseated the connectors on the power lock/latch assembly - no luck.

I can not figure out why the lock will not function with the door closed but works fine when I simulate all aspects of it being closed. What am I missing????
