Window Motor
To test the current draw of a power window motor, remove the motor and drive assembly from the vehicle. See MOTOR under REMOVAL & INSTALLATION. Connect an external power source (power-pac or a fully charged battery) to the motor with an ammeter, Rotunda Digital Volt-Ohmmeter 007-00001 or equivalent, in series as shown. See Fig 1 . Operate the motor and observe the current draw. The current draw for the no-load test should not exceed 5 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 5 Amps.
