POWER WINDOW MAIN SWITCH INSPECTION

id091200002100

Auto-open/close Function (Front Door Type)

  Note
  • Before proceeding with diagnosis of malfunctioning power windows, ensure the POWER WINDOW INITIALIZATION PROCEDURE has been performed.

1. Disconnect the negative battery cable.

2. Remove the inner garnish. (driver-side) (See INNER GARNISH REMOVAL/INSTALLATION.)

3. Remove the front door trim. (driver-side) (See FRONT DOOR TRIM REMOVAL/INSTALLATION.)

4. Connect the power window main switch connector.

5. Connect the negative battery cable.

6. Measure the voltage at each terminal.

  • If the voltage is not as specified in the Terminal Voltage Table, inspect the parts under “inspection item(s)” and related wiring harnesses.

7. If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the power window main switch. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)
