3. Rear Windows Malfunction

Circuit/System Description

When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the driver window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing the window to open. When the driver window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction and the window closes. The driver window switch also controls the passenger windows.

When the ignition switch is in the RUN or ACCY position, or RAP is enabled and the lockout switch is disengaged, battery positive voltage will be available at the passenger window switches. When an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch.

1. Driver Power Window Inoperative

2. Passenger Power Window Inoperative

Circuit/System Description

The vehicle is equipped with power windows controlled by power window electronic (PWE). The passenger door window can be operated, either from a power window switch built into the driver door switch assembly, or from a power window switch mounted on the passenger door.

When the driver PWE receives a driver door window switch request from the driver window switch, the PWE will apply power and ground to the driver door window motor to move the window as requested.

When the passenger PWE receives a window switch request from either the driver door window switch or passenger door window switch, the passenger PWE will apply power and ground to the passenger window motor to move the window as requested.

Normalization enables the PWE to detect the actual position of the window glass in relationship to the total distance traveled by the window. This information is crucial for the proper operation of the system. Normalization means that the PWE stores the end position (window in the full up position) after the complete up travel. The electronics shall store this end position once it has been detected that the window has reached the full up position and the user has applied the up function of the switch continuously for a minimum of 0.5 second.

The window indexing feature is used to lower the driver and passenger power windows approximately 4 mm when the door is opened. This is necessary to allow the top edge of the window to clear the window weatherstrip. This feature will also raise the window to the fully seated position once the door is closed.
