Power to the power windows comes from a 30A Power circuit breaker. This power then goes to power main relay then to the PW master switch.
The solenoid of the power main relay is powered by the Gauge fuse which is powered when the ign key is on.
The power window power wiring splits at the master PW switch. One wire goes to the PW master switch another goes to each of the individual window switches. This allows the power windows to be controlled by the PW master switch and the individual window switch.
If any of the individual window switches work or any of the switches on the master PW switches work, power is getting through the Power breaker and main power relay.
If the individual window switches do not work but the master switch works would suspect a wiring issue. It is common for the wiring between the drivers door and chassis to break due to constant flexing from door usage. The 12V power wiring is blue for both the master switch and individual window switches.
You might check the blue wire at any of the individual window switches. There should be power any time the master PW switch is powered as both receive power from the same source.
Power locks are powered by the same 30A Power breaker.
Automatic shoulder belt powered by 30A Automatic shoulder belt breaker.
Power to the both of these breakers comes from the battery, through an 80A fusible link inside the fusible link box, then another fusible link. Same power goes to ign switch to power radio, wiper, turn signal and more. If power is getting to these items it should be getting to the two breakers.
Suggest first starting with checking for wiring breaks at the drivers harness between door and chassis as this may solve your problems.
