It may not be the power motor see if the motor is grounded look for a strap going to the top of the firewall it should look like a metal strap.Make sure it is tight and not broken. If this is not the problem then it may bne the reostate in the wiper control. If so see a garage or dealer.

Check power to window switch. Common cause. Check power to window motor. If none then check fuses/relays.
