NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK: Go to Next Step 

1. Remove the motor.
2. Inspect the operation of the power window regulator motor (for driver side door).
   NOTE:

   • Be sure not to apply battery voltage to terminals 3 (PLS), 4 (LMT) and 5 (E) of the power window regulator motor LH connector, because it might damage the pulse sensor and the limit switch.
   • Be sure to reset the power window regulator motor (to the initial setting of the limit switch) when the power window regulator motor LH is installed to the regulator.
   1. Check that the motor operates smoothly when the battery voltage is applied to each terminal of the connector.
