POWER WINDOW MAIN SWITCH INSPECTION

id091200419000

1. Switch the ignition ON.

2. Verify that the door glass (driver-side) can be operated for approx. 43 s after the ignition switch is turned to the LOCK position.

• If the door glass (driver-side) cannot be operated for approx. 43 s after the ignition switch is turned to the LOCK position, of if the door glass (driver-side) can still be operated after approx. 43 s, replace the power window main switch.

3. Disconnect the negative battery cable.

4. Remove the inner garnish. (See INNER GARNISH REMOVAL/INSTALLATION.)

5. Remove the front door trim. (See FRONT DOOR TRIM REMOVAL/INSTALLATION.)

6. Remove the switch panel. (See FRONT DOOR TRIM DISASSEMBLY/ASSEMBLY.)

7. Connect the power window main switch connector.

8. Connect the negative battery cable.

9. Measure the voltage at each terminal (except terminals 1A and 1B).

• If the voltage is not as specified in the terminal voltage table, inspect the parts under Inspection item(s) and related wiring harnesses.
