Front Passenger's Power Window Switch Input Test

  1. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, open and close the driver's door, then remove the front passenger's door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION )
  2. Disconnect the front passenger's power window switch 37P connector (A) from the front passenger's power window switch (B)

  3. 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
  4. With the connector still disconnected, do these input tests at the following 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
    TEST CONDITION CAVITY CHART

    Cavity Wire Test condition Test Desired result Possible cause if desired result is not obtained
    12 RED Under all conditions, connect terminals No 25 and No 24 (or No 12), and terminals No 12 (or No 24) and No 37 with jumper wires Check front passenger's power window motor operation The front passenger's power window should open (or close)
    • Faulty front passenger's power window motor
    • An open or high resistance in the wire
    24 BLU
    25 GRN Under all conditions Measure the voltage to ground There should be battery voltage
    • Blown No 13 (20 A) fuse in the passenger's under-dash fuse/relay box
    • Faulty driver's under-dash fuse/relay box
    • Faulty passenger's under-dash fuse/relay box
    • An open or high resistance in the wire
    29 PNK Under all conditions, disconnect the power window master switch 37P connector Check for continuity between front passenger's power window switch 37P connector terminal No 29 and power window master switch 37P connector terminal No 27 There should be continuity An open in UART the wire
  5. Reconnect the front passenger's power window switch connector to the front passenger's power window switch, and do these input tests at the following connector
    TEST CONDITION CAVITY CHART

    Cavity Wire Test condition Test Desired result Possible cause if desired result is not obtained
    37 BLK In all ignition switch positions or all power modes Measure the voltage to ground There should be less than 0 2V
    • Poor ground (G405) or open in ground wire
    • An open in the wire
    26 BRN Ignition switch ON (11), or power mode ON Measure the voltage to ground There should be battery voltage
    • Faulty front passenger's power window switch
    • A short to ground in the wire
    27 GRN Ignition switch ON (II), or power mode ON, and front passenger's power window switch moving up or down Measure the voltage between terminals No 27 and No 37 An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2 5V while the window moves)
    • Faulty front passenger's power window switch
    • Faulty front passenger's power window motor
    • An open or high resistance in the wire
    • A short to ground in the wire
    28 ORN Ignition switch ON (II), or power mode ON, and front passenger's power window switch moving up or down Measure the voltage between terminals No 28 and No 37 An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2 5V while the window moves)
    • Faulty front passenger's power window switch
    • Faulty front passenger's power window motor
    • An open or high resistance in the wire
    • A short to ground in the wire
    36 GRY Under all conditions, disconnect the front passenger's power window motor 6P connector Check for continuity to ground There should be continuity
    • Poor ground (G401) or open in ground wire
    • An open or high resistance in the wire
  6. Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT )
