If power windows, it could be that door switch,the fuse,the relay, the driver side switch, the motor with in the door or loose parts in the regulator. Test the motor first, see if it's getting power (12v) , if so use test leads with the connector removed and see if you can operate the motor without either switch, both directions. If motor is fine use the jumpers to test each of the switches. If no problem found, physically pull up on glass and check for a lot of play in cables, If found replace regulator assembly. If manual only the crank gear or the regulator can be the culprit. Haynes manual has great wiring drawings to use as a guide (color coded)
