Power Window Motor: Description and Operation

SYSTEM OPERATION
A permanent magnet reversible motor moves the window regulator through an integral gearbox mechanism. A positive and negative battery connection to the two motor terminals will cause the motor to rotate in one direction. Reversing the current through these same two connections will cause the motor to rotate in the opposite direction. In addition, each power window motor is equipped with an integral self-resetting circuit breaker to protect the motor from overloads.

The power window motor and gearbox assembly on this model are mounted to the outside of the front door module. This arrangement provides for easy access to the power window motor for service, without removing the window regulator or glass from the door.

The power window motor and gearbox assembly cannot be repaired and, if faulty or damaged, the entire power window motor assembly must be replaced.
