Checking the input signal of the main switch (combi).
Note: The control unit is built into the main window switch and controls the driver's door window only.
1. Remove the power window master switch and armrest pocket from the door panel.
2. Disconnect the 12K connector from the main window switch.
3. Inspect the connectors and socket contacts to ensure that they are in good contact. If the contacts are bent, loose or corroded, correct this and retest the system.
- If the contacts are OK, perform the following tests on the input signal at the connector.
- If any of the tests identify a problem, find and correct the cause, then test the system again.
- If all input tests are positive, the power window master switch is faulty, replace.
