To test the current draw of a power window motor, remove the motor and
drive assembly from the vehicle as outlined.
Connect an external power source (power-pac or a fully charged battery) to
the motor with an ammeter such as Rotunda Digital Volt-Ohmmeter 007-00001 or
equivalent, in series.
Operate the motor and observe the current draw. The current draw for the
no-load test should not exceed specification 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 at 12.8 volts.
