Power Window Control System: Inspection

  1. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSY 
    1. Check the continuity between each terminal of the connector.
      NOTE: Whether the operation is good or bad can be judged by the basic function check, because the continuity cannot be checked by UP/DOWN operation of the driver side switch.

  3. INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH 
    NOTE:
    • Be sure not to apply battery voltage to terminals 2, 3 and 6 of the power window regulator motor assy LH connector, because it might damage the pulse sensor and the limit switch.
    • Be sure to reset the power window regulator motor assembly (initial position setting of the limit switch) when the power window regulator motor assy LH is installed to the regulator.
    1. Inspect operation of the front LH power window regulator motor assembly.
      1. When adding battery voltage to each connector terminal, check that the motor operates smoothly.
