1993 Bighorn Passenger window not working
There could be a lock controller somewhere that is not working.
I don't have a wiring diagram for your truck.
Generally, the power window motors are grounded thru the doors, or the switches provide ground. In your case the motors are probably grounded thru the doors.
The master switch "overrides" the door switch so you have extra wires that do the same thing. The E wire probably gives the door switch power and the A and C are up and down. The B and D are override circuits from the master that bypass the door switch.
Sometimes the motor is grounded thru the switch then thru the door.
