      1. Remove the power window regulator motor assembly.
      2. Apply battery voltage to the motor terminals.
        NOTE: Do not apply voltage to the terminals except 1 and 2.
      3. Check that the motor operates smoothly.

        OK 

        DRIVER SIDE POWER WINDOW OPERATION CONDITIONS

        Measurement Condition Specified Condition
        Battery positive (+) → Terminal 2 (U)
        Battery negative (-) → Terminal 1 (D)        		 Motor gear rotates clockwise
        Battery positive (+) → Terminal 1 (D)
        Battery negative (-) → Terminal 2 (U)        		 Motor gear rotates counterclockwise
    2. Check the PTC operation inside the regulator motor.
      NOTE: The work must be performed with the power window regulator and door glass installed in the vehicle.
      1. Disconnect the driver side power window regulator motor connector.
      2. Connect the ammeter's positive (+) lead to terminal 1 (D) of the wire harness side connector and the negative (-) lead to the battery's negative terminal.

      3. Connect the battery's positive (+) lead to terminal 2 (U) of the wire harness side connector, and raise the window to the fully closed position.
      4. Continue to apply voltage, and check that the current changes to less than 1 A within 4 to 90 seconds.
      5. Disconnect the leads from the terminals.
      6. Approximately 60 seconds later, connect the battery's positive (+) lead to terminal 1 (D) and the negative (-) lead to terminal 2 (U). Check that the window begins to descend.

        If the result is not as specified, replace the motor assembly.
