1. Driver Window Malfunction 2. Passenger Window Malfunction 3. Left Rear Window Malfunction 4. Right Rear Window Malfunction |
The front and rear power windows are controlled by the driver door lock/window switch and passenger door lock/window switch. The driver door lock/window switch and passenger door lock/window switch each contain power window switches that are integrated into the module. The driver door lock/window switch contains the master power window switches that control all power window operations. The power window switch contained in the passenger door lock/window switch controls the front passenger window operation only.
When the driver power window switch is activated to a desired position, the driver door lock/window switch examines the request and checks for messages from other vehicle control modules prohibiting window movement. If no prohibitive messages have been received, the driver door lock/window switch will send a serial data message to the driver door window motor to move the window to the desired position.
When the driver door lock/window switch receives a request to operate the right side passenger windows from the master switch, a serial data message is sent to the passenger door lock/window switch. The passenger door lock/window switch examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the passenger door lock/window switch will send a serial data message to the appropriate window motor to move the window as requested.
When the driver door lock/window switch receives a request to operate a rear window from the master switch, a serial data message is sent to the BCM. The BCM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the BCM will send a serial data message to the appropriate rear window switch which will command the window motor as requested.

1. Driver Window Malfunction 2. Passenger Window Malfunction 3. Left Rear Window Malfunction 4. Right Rear Window Malfunction |
The driver and passenger door lock and side window switches are integrated control module switch assemblies. The driver door lock/window switch controls the passenger window through a serial data message to the passenger door lock lock/window switch. When a power window switch is activated in the up or down positions the driver door lock/window switch or passenger door lock lock/window switch supplies power and ground to their respective window motor control circuits to drive the window motor in the required direction. The rear passenger power windows can also be operated from the driver door lock/window switch through a serial data message to the BCM. The rear passenger window switches on the driver door lock/window switch have 2 positions, up and down, their position is a direct input into the driver door lock/window switch. When the BCM receives a command to operate a rear window up or down, the appropriate signal is sent to the rear door window switch which will command the window motor to perform the up or down function.
Each power window contains a reversible power window motor. The direction the window travels is dependent upon the polarity of the supply voltage. By reversing polarity of the supply voltage the window motor will move up or down. Each power window motor is internally circuit breaker protected.
