Hi, I've got a 73 Mach 1 with a 351 CJ, and while driving across the country my windows stopped working. No blown fuses, all fusible links still have power running through them. They went down when I started driving, but somewhere during the drive they stopped working. None of the switches work. And now back in ca with these rain storms I can't go anywhere cuz the windows don't go up. Any ideas?

 

First idea, take off the door panel and tap them with something while manipulating the switch. Second idea, try running power directly to the motor and see if that helps. Third idea, if the first 2 don't work, replace the motors.

 

The fact that all the windows stopped working is a strong indication that the problem lies ahead of or at the master switch. The chance that all switches went bad at once is nil. Don't waste your time at the motors. You've got to have the wiring diagram to split the circuit and properly trace back.
I see a power window relay ahead of the master switch, I'd start there and make sure power is going to the master switch.
