Component Inspection

INSPECTION





1. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
a. Remove the master switch.
b. Measure the resistance between the terminals of the connector when the switch is operated.







Standard:




c. Check the AUTO lamp master switch.

Standard:

If the result is not as specified, replace the master switch assembly.




2. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY
a. Remove the power window regulator switch.
b. Measure the resistance between the terminals of the connector when the switch is operated.

Standard:

If the result is not as specified, replace the regulator switch assembly.




3. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY
a. Check motor operation of the regulator motor.

HINT:
- The front LH and rear RH regulator motors should be inspected using the same procedure.
- The front RH and rear LH regulator motors should be inspected using the same procedure.

1. Remove the power window regulator motor.
2. Apply battery voltage to the motor terminals.
3. Check that the motor operates smoothly.

NOTE: Do not apply voltage to the terminals except 1 and 2.




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




b. 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 battery's negative terminal.
3. Connect the battery's positive (+) lead to terminal 1 of the wire harness side connector, and raise that window to the fully closed position.
4. Continue to apply voltage, and check that the current changes to less than 1A 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 lower.

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




4. INSPECT RELAY (IG1)
a. Remove the IG1 relay from the instrument panel J/B.
b. Measure the resistance.

Standard:

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