Chevrolet Repair: Suburban door locks., door switches, wiring diagrams

Question
1994 Suburban 2500.

Doors will unlock with either front door switches, will not lock. The relay only continues to click until the switch is recycled to the unlock position.  Replaced relay, same problem. Have pulled a couple of door panels, can't reach the lock motors to disconnect for troubleshooting.  Having a real hard time obtaining wiring diagrams.  Does this sound like a door lock motor to you?  As I said, all of the doors will unlock with either switch, even after manually locking all doors.

Thanks
Roy

Answer
Hi Roy, It is not the lock motors because they work to unlock the door. The problem has to be in the control unit, maybe there are 2 relays. One for the lock and one for the unlock. I'm thinking it's not the switches because they both do the same thing. You need a wire diagram to really see how the circuit works.

Sorry I can't help more
