If the motor is humming when you hit the switch it has power. Sounds like either a wiring issue or 1 or more switches are bad. I don't know about these vehicles, but my '86 mustang had an issue like this (the rear quarter windows wouldn't go down) and it actually turned out to be the "master" switch in the driver's door that was causing the issue.

Good luck...I hate electrical gremlins.
