1. Driver Window Malfunction

2. Passenger Window Malfunction

Circuit/System Description

The window motors are supplied with B+ voltage which is used to power the motor and also used as a reference voltage within the logic circuit. When the driver window switch is pressed, a switch is closed causing the reference voltage in the appropriate circuit in the window motor to drop, the window motor responds by moving the window in the direction commanded.

1. Front Window Malfunction

2. Rear Window Malfunction

Circuit/System Description

When the left rear, right rear or right front window switch is pressed on the driver window switch, a serial data message is sent to the body control module (BCM). The BCM examines the request and checks for messages from other power window motors prohibiting the window movement. If no prohibitive messages have been received, the BCM will send a serial data message to the appropriate passenger or rear window motor which will perform the command as requested.

Each power window motor is controlled by their respective window switches. When a power window switch is activated to a desired position, power window switch will send a signal to its respective door window motor to move the window to the desired position.
