Checking the Power Window Mechanism
Checking the power window mechanism
Checking the limit position
Check that the window reaches its upper limit position.
Does the window reach its upper limit position?
Yes - Checking components and wiring
No - Checking the window controls
-------------------------------------------------
Checking components and wiring
Check that fuse 11C/35 or 11C/36 in the passenger compartment integrated relay / fusebox is intact.
Check the cable between control module terminal #4B and the power window motor #3. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Check the cable between control module terminal #3B and the power window motor #6. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Check the cable between control module terminal #16A and the power window motor #4. Check for a short-circuit to ground. Check for an open-circuit. Check for a short-circuit to supply voltage.
Check the cable between control module terminal #19A and the power window motor #1. Check for a short-circuit to ground. Check for an open-circuit. Check for a short-circuit to supply voltage.
Check the cable between control module terminal #7B and the battery. Check for a short-circuit to ground. Check for an open-circuit.
Check the cable between control module terminal #5B and ground: Left or right front seat support. Check for a short-circuit to ground. Check for an open-circuit.
Replace the cable if a fault is found.
- Ignition on
- Try to operate the window lift mechanism to its limit positions (manually and automatically).

- After checking all wiring (and replacing faulty wiring), pass a current across the motor and check that it operates
- Checking wiring and terminals Checking Wiring And Terminals.
Was a fault detected?
Yes - FAULT FOUND
No - Checking the voltage
-------------------------------------------------
Checking the window controls
Press the VCT2000 symbol. Read off to check that the automatic window controls for up and down are functioning on the front door controls.
Hint: Automatic window control is achieved by moving the control two stages.
Do the controls function?
Yes - Reinitiating the window positions
No - Replacing the component
-------------------------------------------------
Replacing the component
Caution! A new driver/passenger door module (DDM/PDM) is supplied without software. The control module must be programmed when it has been replaced. For further information about programming and replacing the control module, see Driver's door module / passenger door module (DDM/PDM), replacing Driver's Door Module/Passenger Door Module (DDM/PDM), Replacing.
After replacing the control module the window position must be initialized.
Move the window to its upper limit position using manual control.
Initialize the window.
From model year 2003 inclusive, the window will lower approximately 10 centimeters and then close again during initialization.
Continue - FAULT FOUND
-------------------------------------------------
Checking the voltage
- Ignition on.
Activate the power window lift motor and take a reading across the motor. Voltage should be 12 V.
Other information:
- To access and replace the power window mechanism, see Window lift mechanism front side door, replacing Service and Repair.
Is the voltage 12V?
Yes - Replacing the component
No - Replacing the component
-------------------------------------------------
Replacing the component
Replace the window lift mechanism. See Window lift mechanism front side door, replacing Service and Repair.
- Ignition on
- Move the window to its upper limit position using manual control
- Initialize the window
- From model year 2003 inclusive, the window will lower approximately 10 centimeters and then close again during initialization
- Try to operate the window lift mechanism to its limit positions (manually and automatically).
Does the window lift mechanism operate?
Yes - FAULT FOUND
No - No Fault Found
-------------------------------------------------
Reinitiating the window positions
Move the window to its upper limit position using manual control.
Initialize the window.
From model year 2003 inclusive, the window will lower approximately 10 centimeters and then close again during initialization.
Continue - FAULT FOUND
