Inspect Power Window Regulator Motor Assembly LH
1. Inspect the front LH power window regulator motor assembly operation.
  NOTE:
  - Do not apply the battery voltage, because the pulse sensor and limit switch could be damaged if the battery voltage is applied to terminals 2, 3 and 6 of the power window regulator motor connector.
  - Be sure to reset the power window regulator motor (initial position setting of limit switch) when the driver's side power window regulator motor is installed to the regulator.
  1. Check that the motor operates smoothly when the battery positive voltage is applied to each terminal of the connector.

2. Inspect the PTC operation inside power window regulator motor.
  NOTE: Inspection should be done with the power window regulator and door glass installed to the vehicle.
  1. Set a DC 400 A probe of electrical tester in the wire harness of terminal 4 or 5.
    NOTE: Match the arrow mark of the probe with the current direction.
  2. Set the door glass in the fully closed position.
  3. When 60 seconds have elapsed after the door glass is fully closed, check the changing time of the current, from approximately 16 - 34 A into 1 A or less, when the power window switch is turned UP once again.
    1. Standard: Approximately 4 - 90 seconds
  4. When approximately 60 seconds have elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator switch is turned DOWN.
1. OK: Repair Or Replace Harness And Connector
2. NG: Replace Power Window Regulator Motor Assembly LH
