Power Window Motor

Troubleshooting Hints:

To test the current draw of a power window motor, remove
the motor and drive assembly from the vehicle.

Test Procedure

1. Connect an external power source (power-pac or a fully charged battery) to the motor with an ammeter such as Rotunda Digital Volt Ohm Meter 007-00001 or equivalent, in series.

2. Operate the motor and observe the current draw. The current draw for the no-load test should not exceed 5 amps at 12.8 volts 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 specification.
