DIAGNOSTIC FAULT INFORMATION

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.

CIRCUIT/SYSTEM VERIFICATION
1. Ignition ON, command the appropriate door window UP and DOWN by pressing the appropriate window switch. Observe the operation of the appropriate door windows.
- If all power windows are inoperative, refer to All Power Windows Inoperative.
- If the driver door window or passenger door window is inoperative, refer to Power Window Inoperative.
2. Ignition ON, command the express down function for the appropriate door window by pressing Auto on the appropriate window switch located on the driver window switch past the first detent and releasing.The appropriate window should roll completely down.
- If the appropriate window fails to roll completely down, replace the driver window switch.

CIRCUIT/SYSTEM TESTING

All Power Windows Inoperative
1. Ignition OFF, disconnect the harness connector at the applicable window switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal and ground.
- If the test lamp does not illuminate, test the B+ circuit for an open/high resistance. If the ROOF/HEAT SEAT fuse is open, check the B+ circuit for a short to ground. If the circuit tests normal, test or replace the retained accessory power (RAP) relay.
- If all circuits test normal, test or replace the applicable window switch.
3. Ignition OFF, disconnect the applicable window motor.
4. Ignition ON, verify that a test lamp illuminates between the appropriate window motor B+ circuit terminal 6 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground. If the circuit tests normal and the PWR WDO CPE/CONV circuit fuse is open, replace the applicable window motor.

Power Window Inoperative
1. Ignition OFF, disconnect the B+ harness connector at the driver window switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 3 and ground.
- If the test lamp does not illuminate, test the B+ circuit for an open/high resistance. If the ROOF/HEAT SEAT fuse is open, test the circuit terminal 3 for a short to ground.
- If all circuits test normal, test or replace the driver window switch.
3. Ignition OFF, connect the harness connector at the driver window switch.
4. Ignition OFF, disconnect the passenger window switch.
5. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal A and ground.
- If the test lamp does not illuminate, test the B+ circuit for an open/high resistance.
6. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal H and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the driver window switch.
7. Ignition OFF, test for less than 1 ohm of resistance between the control circuit terminal D and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the driver window switch.
8. Connect a test lamp between control circuit terminal H and control circuit terminal D.
9. Ignition ON, command the passenger door window UP and DOWN by pressing the passenger window control on the driver window switch. The test lamp should illuminate during either of the commands.
- If the test lamp remains OFF, test for a short to ground or open/high resistance on either control circuit. If all circuits test normal, test or replace the driver window switch.
10. Ignition OFF, reconnect the passenger window switch.
11. Ignition OFF, disconnect the harness connector at the appropriate window motor.
12. Test for less than 1 ohm for resistance between the appropriate window motor ground circuit terminal 4 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
13. Ignition ON, verify that a test lamp illuminates between the appropriate window motor B+ circuit terminal 6 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, replace the applicable window motor.
14. Ignition OFF, test for less than 1 ohm of resistance between the control circuit terminal 1 and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, test or replace the appropriate window switch.
15. Ignition OFF, test for less than 1 ohm of resistance between the control circuit terminal 2 and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, test or replace the appropriate window switch.
16. Connect a test lamp between control circuit terminal 1 and control circuit terminal 2.
17. Ignition ON, command the appropriate window UP and DOWN by pressing the appropriate window switch. The test lamp should turn ON when commanding the UP and DOWN states.
- If the test lamp remains OFF during either of the commands, test for a short to ground on either control circuit. If all circuits test normal, test or replace the appropriate window switch.
18. If all circuits test normal, replace the applicable window motor.
