Use a multimeter to verify power at the switch, then verify power at the motor connection (make sure you have the ignition key on, I've made the mistake of leaving it off while doing power checks).
If you've got power into the switch but not out, bad switch.
Power into the motor but no reaction, bad motor.
I suspect in your case tho you have a bad fuse holder or shorted wire powering the system. This will be in your fuse block under the dash.
