   Is the inspection result normal? 

   YES: Replace power window main switch. Refer to "REMOVAL AND INSTALLATION ".

   NO: GO TO 2.

2. CHECK ENCODER SIGNAL CIRCUIT
   1. Turn ignition switch OFF.
   2. Disconnect power window main switch connector and driver side power window motor connector.
   3. Check continuity between power window main switch harness connector and driver side power window motor harness connector.
