The door locks and the driver window all receive power from the Vehicle security module (VSM). The fuse to the VSM is # ***** in the under dash fuse box. The first step is to check that fuse to see if it is blown.
Ok. Do you have a multi-meter or test light to check for voltage at fuse #30? If you have voltage then there is likely a break in the wire from the fuse to the VSM.
Trace the circuit from fuse 30. The Dark Green wire comes out of the inside fuse box on pin 8 of connector C270d, an 8-terminal connector on the rear of the fuse box. From there, it goes through pin 7 of C211, a 14-terminal connector behind the passenger side of the dash, above the VSM. It then runs to splice S391, near the bottom of the passenger side kick panel, where it split off to the VSM and to the driver window motor.
No, if you don't have voltage then the fuse box or the wire running to the fuse box is the problem. This fuse supplies voltage to the VSM so if you do have voltage there then you have to trace it to the VSM and see if the voltage is at the VSM as well. If not then the problem is in that wire or the harness to the VSM. If you have voltage at the VSM as well then the VSM could be faulty.
