Wait, when you lock your doors from either door (using the power switch ) the passenger's door doesn't lock? Can you lock it with the key on the outside?
Does it make any noise?
Have you tried locking all the doors manually (push the lock lever, not the lock button) on all the doors except the passenger's door? And then trying a switch? I ask because I'm curious as to whether the motor is running or not....
Windows work okay?
