INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER WINDOW REGULATOR SWITCH ASSEMBLY (REAR LH) (POWER SOURCE)





(a) Disconnect the I1 power window regulator switch assembly connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:





(c) Reconnect the I1 power window regulator switch assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (REAR LH)





(a) Remove the power window regulator switch assembly.
(b) Measure the resistance of the switch when the switch is operated.
Standard resistance:





(c) Reinstall the power window regulator switch assembly.
NG -- REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY (REAR LH)
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (SWITCH (REAR LH) - MOTOR (REAR LH))
(a) Disconnect the I1 power window regulator switch assembly connector.





(b) Disconnect the I2 power window regulator motor assembly connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:





(d) Reconnect the I1 power window regulator switch assembly connector.
(e) Reconnect the I2 power window regulator motor assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH)





(a) Remove the power window regulator motor assembly.
(b) Apply battery voltage to connector terminals 1 and 2.
(c) Check that the motor gear rotates smoothly as follows.
OK:





(d) Reinstall the power window regulator motor assembly.
NG -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - SWITCH (REAR LH))
(a) Disconnect the G1 power window regulator master switch assembly connector.





(b) Disconnect the I1 power widow regulator switch assembly connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:





(d) Reconnect the G1 power window regulator master switch assembly connector.
(e) Reconnect the I1 power window regulator switch assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY (REAR LH SWITCH)





(a) Inspect the rear LH switch.
(1) Remove the power window regulator master switch assembly.
(2) Measure the resistance of the switch when the switch is operated.
Standard resistance:





(b) Reinstall the power window regulator master switch assembly.
NG -- REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
OK -- GO TO POWER WINDOWS DO NOT OPERATE AT ALL
