INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (POWER SOURCE)

(a) Disconnect the P10 regulator switch connector.
(b) Turn the ignition switch ON.
(c) Check the voltage between the terminal 4 of the wire harness side connector and the body ground.
Standard voltage:
10 to 14 V

NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR (SWITCH - RELAY)
OK -- Continue to next step.

2. INSPECT POWER WINDOW REGULATOR SWITCH (REAR LH)

(a) Remove the regulator switch.
(b) Check the resistance between the switch terminals when the switch is operated, as shown in the table below.
Standard resistance:

NG -- REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY REAR (REAR LH)
OK -- Continue to next step.

3. CHECK WIRE HARNESS (SWITCH - MOTOR) (SWITCH - BODY GROUND)

(a) Disconnect the P14 motor connector.
(b) Check the resistance between the wire harness side connectors.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH (REAR LH)

(a) Remove the motor.
(b) Apply battery voltage to connector terminals 1 and 2.
(c) Check that the motor smoothly rotates.
Standard:

NG -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY LH (REAR LH)
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (MASTER SWITCH - SWITCH)
