Left Rear Power Window Switch Input Test
- Remove the left rear power window switch (see REAR PASSENGER'S ).
- Disconnect the 14P connector (A) from the left rear power window switch (B).
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 4.
- With the connector still disconnected, make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.
SYMPTOM CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 3 LT GRN Power window master switch 22P connector disconnected Check for continuity between the No. 3 terminal and power window master switch 22P connector No. 13 terminal:
There should be continuity.An open in the wire Check for continuity to ground:
There should be continuity.A short to ground in the wire 8 RED Connect the No. 8 terminal to battery power with a jumper wire, and connect the No. 14 terminal to ground. Check the left rear power window motor operation:
The motor should run (the window should go down).- Faulty left rear power window motor
- An open in the wire
14 BLU Connect the No. 14 terminal to battery power with a jumper wire, and connect the No. 8 terminal to ground. Check the left rear power window motor operation:
The motor should run (the window should go up).- Faulty left rear power window motor
- An open in the wire
- Reconnect the connector to the left rear power window switch, and make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the left rear power window switch must be faulty; replace it.
