Power Window Rear Switch Input Test
With all power windows AUTO UP/AUTO DOWN function
  1. Turn the ignition switch to LOCK (0), and remove the rear power window switch.
  1. Disconnect the 14P connector (A) from the rear power window switch (B).
    NOTE: The illustration shows left rear power window.
  1. 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 .
  1. 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 .

  1. Reconnect the connector to the rear power window switch, turn the ignition switch to ON (II), 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, replace the rear power window switch.
    NOTE: After replacing the switch, reset the power window control unit.
