Window Motor

With motor removed from vehicle, connect a fully charged battery to motor with an ammeter in series. Current draw for this no load test should not exceed 5 amps @ 12.8 volts, and should not fluctuate. Reversal of battery connections should reverse the rotation of motor, while the current draw should remain the same. Replace motor if current draw exceeds specifications. With motor installed, normal current draw should be about 12 amps. With window against a stop, current draw should be about 20 amps.
