      Battery Positive (+) --> Terminal 1(D)
      Battery Negative (-) --> Terminal 2 (U)      		 Motor gear rotates clockwise
      Battery Positive (+) --> Terminal 2 (U)
      Battery Negative (-) --> Terminal 1 (D)      		 Motor gear rotates counterclockwise

    2. Check operation of the PTC inside the regulator motor.
    NOTE: Work must be performed with the power window regulator and door glass installed to the vehicle.
    1. Set an electrical tester DC 400 A probe to the wire harness of terminal 2.
      NOTE: Match the arrow mark of the probe with the current direction.
    2. Fully close the door glass by operating the power window switch and keep the door glass there for approximately 60 seconds.
    3. With the door glass fully closed, operate the power window switch in the closing direction again. Check how long the current takes to change from a range of 16 A to 34 A, to less than 1 A.

      Standard: 4 to 90 seconds 

    4. Check that the door glass moves down when the power window regulator switch is pushed DOWN.

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