INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH
CAUTION:
- 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 (See step 24 under OVERHAUL ).
1. Inspect operation of the front LH power window regulator motor assembly.

2. Check operation of the PTC inside the power window regulator motor.
  NOTE: Work must be performed with the power window regulator and door glass installed to the vehicle.
  1. Set the DC 400 A probe to terminal 4 or 5 of the wire harness.
    NOTE: Match the arrow mark of the probe with the current direction.
  2. Set the door glass at the fully closed position.
  3. When approximately 60 seconds have passed after fully closing the door glass, check how long the current takes to change from approximately 16 - 34 A to less than 1 A when pulling the power regulator switch UP furthermore (at initial time).
    Standard: Approximately 4 - 90 seconds
  4. When approximately 60 seconds have passed after the cut-off check, check that the door glass goes down when the power regulator switch is pressed DOWN.
INSPECT POWER WINDOW REGULATOR MOTOR ASSY RH
1. Inspect operation of the front RH power window regulator motor assembly.
