Component Tests and General Diagnostics
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 the components and wiring
No - Checking the window controls
-------------------------------------------------
Checking the components and wiring
Check that the fuses are 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. 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).

Was a fault detected?
Yes - FAULT FOUND
No - Checking the voltage
-------------------------------------------------
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
- 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
-------------------------------------------------
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.
Continue - FAULT FOUND
-------------------------------------------------
Checking the window controls
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
-------------------------------------------------
Reinitiating the window positions
Move the window to its upper limit position using manual control.
Initialize the window.
Continue - Verification
-------------------------------------------------
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Move the window lift mechanism to its limit position, including automatic control.
Are the controls working?
Yes - Verification complete
No - Fault-tracing information
-------------------------------------------------
Fault-tracing information
Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing
No - Attempt New Test
