    '74 Power window problem

    Suddenly the power windows stoped working, my wiring diagram says they are on a circuit breaker, not a fuse, does anyone know where this breaker is located an what it looks like? Also how do I reset it or do I replace?
    Thanks in advance for your help!

    Circuit breakers are, by definition, self-resetting. Once the power overload is removed, an internal bi-metal contact cools and the circuit 'makes' once again.

    The most common cause for sudden failure of both power windows is a cockpit issue... The driver managed to 'kick' the fuse block and knocked the plug-in power receptical off the fuse block's AUX power terminal.

    Your copy of the AIM (Assembly Instruction Manual) ought to show you where the circuit breaker is physically located. Look in the rear of the book under option A31. On earlier Shark cars it was bolted to the firewall in the engine compartment to the right of the wiper motor. I'm not sure if it got moved when the body was simplified to remove the wiper door assy....
