1. wiring diagrams for driver side front and rear door lock actuators.

problem: door locks won't work (rear one does not move at all while front lock seems to slightly respond to power switch but does not lock or unlock (just slight movement in the door's knob is observed).

2. wiring diagrams for passenger side rear window.

problem:
window does not respond to the power switch at all.

Thanks in advance.

Hello, have you checked the wiring running through the rubber boot between the door(s) and body? I am pulling up the wiring diagrams for you, but the wires in those rubber boots tend to have issues due to the flexing when the door moves.
Diagrams 1 and 2 are the power locks, and 3 and 4 are the power windows.

I added the OEM diagrams as well, 1 and 2 are Power Door Locks, and 3 and 4 are Power Windows. Some of the wire colors looked a little different, so just in case you can compare the colors to these diagrams.
