1.  Switch the ignition to ON.

2.  Verify that the door glass (driver’s side) can be operated for approx. 43 s after the ignition is switched off.

•  If the door glass (driver’s side) cannot be operated for approx. 43 s after the ignition is switched off, or if the door glass (driver’s 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. (driver's side)(See INNER GARNISH REMOVAL/INSTALLATION.)

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

6.  Remove the power window main switch. (driver's side)(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.

•  If the voltage is not as specified in the terminal voltage table, inspect the parts under Inspection item (s) and related wiring harnesses.
―  If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the power window main switch.
