Power Windows - Operation






OPERATION

POWER WINDOWS

The door control modules, (Driver Door Module (DDM) and Passenger Door Module (PDM)) opens or closes the windows when a actuation input signal from the window switch is received from the door trim panel. When the power window lockout switch is in the Lock position, the passenger doors windows switches are disabled. This is only powered when the ignition switch is in the RUN or ACCESSORY position.

If equipped, the windows have the option of auto up/down. If equipped, the four door gets auto-up/down feature, while the two door just gets the auto-down feature.

WINDOW MOTOR

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 cannot be adjusted or repaired. If damaged or ineffective, the entire unit must be replaced.
