Hello all - I have a 1990 F250 and the power windows have stopped working. The passenger side was running pretty sluggishly, then quit altogether, and a day or so later, the drivers side did too. Fuses are OK. Switch does not work on either side. Could both motors have failed?

 

Its possible but I would say the switches has went bad ... You can jump across the wires to the motor and see if they work
