INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSY
1. Remove the master switch (see OVERHAUL ).
2. Measure the resistance of the switch when the switch is operated.

If the result is not as specified, replace the regulator switch assy.
INSPECT POWER WINDOW REGULATOR MOTOR ASSY
1. Check operation of the regulator motor.
  1. Remove the power window regulator motor (see OVERHAUL ).
  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:

  If the result is not as specified, replace the motor assy.
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.
  2. Connect the ammeter's positive (+) lead to terminal 2 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 1 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 2 and the negative (-) lead to terminal 1, and check that the window begins to descend.
If the result is not as specified, replace the motor assy.

INSPECT RELAY (IG1, PWR)

Remove the IG1 and PWR relays from the instrument panel J/B.
Measure the resistance of the relays.

Standard:

RELAYS RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
3 - 5	10 kΩ or higher
3 - 5	Below 1 Ω (when battery voltage is applied to terminals 1 and 2)

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