well i have a keyless entry, so i assume that my driver side has an power lock, 1 week ago when i lock my driver side by hand or by the remote it wouldn't lock the passenger side, so then i thoughts its cool i'll just get some contact cleaner and spray around the area, i did, now the passenger side would lock when locking the driver side, but then when i use the remote it would work sometimes and it would not work sometimes? Anybody know an exact place to spray the contact cleaner? I just spray around the wires, where is the power lock sensor and motor located exactly?

 

There are no stock power locks in the drivers door.

You would have an aftermarket system, so the lock switch and motor could be anywhere that someone put them in. There are about 6 differnt places in the drivers door to attach an aftermarket power door lock motor.
