Power Window Motor
- Disconnect the motor lead.
- Disconnect the regulator mechanism from the motor.
- Supply power to motor lead connector with an ammeter in series. See Fig 1 .
- Operate the motor and observe the current draw. The current draw for the no-load test should not exceed 4 amps and should not fluctuate. Reversal of the motor wire connections will reverse the direction of motor rotation. Replace the motor if the current draw exceeds 4 amps.
