Power Window Front Passenger's Switch Input Test

  1. Turn the ignition switch to LOCK (0), and remove the front passenger's power window switch.
  1. Disconnect the 37P connector (A) from the front passenger's power window switch (B).
  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 .

    Under all conditions, connect No. 25 and No. 24 (or No. 12) terminals, and No. 37 and No. 12 (or No. 24) terminals with jumper wires.
    Check front passenger's power window motor operation: The front passenger's power window should open (or close).

    Under all conditions, disconnect the power window master switch 37P connector, sunroof control unit 14P connector, left rear power window switch 14P connector * , and right rear power window switch 14P connector * .
    Check for continuity between the No. 29 terminal and the power window master switch 37P connector No. 27 terminal: There should be continuity.

    With all power windows AUTO UP/AUTO DOWN function

  1. Reconnect the connector to the front passenger's 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 front passenger's power window switch.
    NOTE: After replacing the switch, reset the power window control unit.
