Power windows not working

Just some basics, new window motors, lubed regulator tracks(Pain in the a**), new drivers door master switch. Still both windows will not work. Does anyone have a wiring diagram so I can chase this thing down??

Have you checked your body control module?

found a wiring diagram and found no power going to the 30amp breaker with key on engine off. Anyone know where I can locate this relay that supplies power to the 30amp breaker in the circuit????

Sorry, don't have a wiring diagram for a 94. However, my guess is with how many times that driver's side door has opened for the last 18 years - could be possible one or more wires is broken where the wires feed from the body of the car into the door.

IIRC, the passenger window will get power from the driver's side/master switch so I bet you have wiring issues going to the master switch and my first place to look would be in that rubber grommet/boot.
