Circuit/System Description

The body control module (BCM) monitors, receives and transmits serial data to each of the doors switches and window motors. When a window switch has been activated on the driver window switch, a signal is sent to the BCM which sends a signal to the appropriate window motor and the window motor will move in the direction commanded.

Conditions for Running the DTC

• The ignition switch is in the ON position.
• Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

B3205 00, B3210 00, B3215 00, B3220 00

The BCM has detected that the compatibility code stored in the affected window motor does not match the compatibility code stored in the BCM.

B3205 39, B3210 39, B3215 39, B3220 39

An internal malfunction has been detected by the BCM in the power window motor while commanding the window UP or DOWN.

B3205 42, B3210 42, B3215 42, B3220 42

The BCM will automatically attempt to download the calibration program into the appropriate window motor (As will occur when the window motor has been replaced), if the first calibration program fails to load, the BCM will attempt to download the calibration program a second time. If this download fails, the BCM will set appropriate DTC.

B3205 4B, B3210 4B, B3215 4B, B3220 4B

The BCM detects that a window motor is "not normalized" which will occur under the following conditions:

• When the battery has been disconnected
• When the battery has been replaced
• When the door wiring harness has been disconnected
• When the window motor has been disconnected

Action Taken When the DTC Sets

B3205 00, B3205 39, B3205 42, B3210 00, B3210 39, B3210 42, B3215 39, B3220 39

The affected motor will be inoperative.

B3205 4B, B3210 4B, B3215 4B, B3220 4B

The affected motor will not perform the express up or express down functions and the driver information center will display Open, then Close Driver Window or will display Open, then Close Passenger Window.

Conditions for Clearing the DTC

B3205 00, B3210 00, B3215 00, B3220 00

Installing a compatible window motor for that specific make and model vehicle.

B3205 39, B3210 39, B3215 39, B3220 39

The appropriate window motor must be replaced before the DTC can be cleared.

B3205 42, B3210 42, B3215 42, B3220 42

The appropriate window motor must be replaced before the DTC can be cleared.

B3205 4B, B3210 4B, B3215 4B, B3220 4B

The appropriate window motor must be normalized before the DTC can be cleared.

Circuit/System Verification

1. Ignition ON.
2. Verify the driver, passenger, left rear and right rear window functions while commanding the Driver Window Motor, Passenger Window Motor, Left Rear Window Motor and Right Rear Window Motor Up and Down with a scan tool.

• If the Up and Down does not work

Replace the appropriate M74 Window Motor.

• If the Up and Down works

3. Verify the driver, passenger, left rear and right rear window performs the Express Up and Express Down functions with the driver window switch.

• If a window does not Express Up and Express Down

Normalize the window motor, refer to Window Motor Programming - Express Function.

• If the window performs the Express Up and Express Down functions

4. All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.

• Front Side Door Window Regulator Motor Replacement
• Rear Side Door Window Regulator Motor Replacement

SYMPTOMS - FIXED AND MOVEABLE WINDOWS

Important Preliminary Checks Before Starting:

1. Perform the Diagnostic System Check - Vehicle before using the symptom tables in order to verify that all of the following are true:

• There are no DTCs set.
• The control modules can communicate via the serial data link.

2. Review the power window system operation or rear window defogger system operation in order to familiarize yourself with the system functions. Refer to the following:

• Rear Window Defogger Description and Operation
• Power Windows Description and Operation

Visual/Physical Inspection

• Inspect for aftermarket devices which could affect the operation of the rear window defogger. Refer to Checking Aftermarket Accessories .
• Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.

Intermittent

NOTE: Inspect for proper installation of electrical components if an intermittent condition exists. Inspect for aftermarket theft deterrent devices, lights, and cellular phones. Ensure that no aftermarket equipment is connected to the class 2 circuit. If you can not locate an intermittent condition, a cellular phone signal may cause the condition. Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections .

The problem may or may not turn ON the SERVICE VEHICLE SOON indicator or store a DTC. Do not use the symptom tables to diagnose intermittent conditions. The malfunction must be present in order to locate the problem.

Poor electrical connections or wiring cause most intermittent conditions. Perform a careful visual/physical check for the following conditions:

• Poor mating of the connector halves or a terminal not fully seated in the connector body
• An improperly formed or damaged terminal
• Reform or replace connector terminals in the problem circuit in order to ensure proper contact tension.
• Poor terminal to wire connection requires removing the terminal from the connector body in order to perform the check.

Use a scan tool in order to help detect intermittent conditions. The scan tool has several features that can be used to locate an intermittent condition. The snapshot feature can capture and store data parameters within the scan tool when the malfunction occurs. This information can then be reviewed in order to see what caused the malfunction.

Symptom List

Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom:

• Rear Window Defogger Malfunction
• Power Windows Malfunction (AXG, AEF, AER), Power Windows Malfunction (AXG, AED, AEQ), Power Windows Malfunction (A55, A66 Without A33), Power Windows Malfunction (A55, A66 With A33), Power Windows Malfunction (AXG, A66, A33)
