   Check operation of the power window motor (driver side).

   1. Remove the motor.
   2. Apply battery voltage to connector terminals 1 and 2.
   3. Check that the motor smoothly rotates.
      NOTE:

      Do not apply battery voltage to any terminals except terminals 1 and 2.

      Standard

      Terminal No.	Specified Condition
      Battery positive (+) → 1 Battery negative (-) → 2	Motor gear rotates counterclockwise
      Battery positive (+) → 2 Battery negative (-) → 1	Motor gear rotates clockwise

NG → REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK → REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (DRIVER SIDE)
