Front Passenger's Power Window Switch Input Test

2013 Acura TL SH-AWD, Automatic TransSECTION 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.
  2. Open and close the driver's door, then remove the front passenger's door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
  3. Disconnect the front passenger's power window switch 37P connector (A) from the front passenger's power window switch (B).

  4. 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 5.
  5. With the connector still disconnected, do the following input tests:
    • 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 6.
      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 the UART 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)
      • An open or high resistance in the ground wire
      Check for continuity between front passenger's power window switch 37P connector terminal No. 36 and front passenger's power window motor 6P connector terminal No. 2: There should be continuity. An open or high resistance in the ground wire
  6. Reconnect the connector to the front passenger's power window switch, turn the ignition to ON(II), or press the engine start/stop button to select the ON mode, and do the following input tests:
    • 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 (see FRONT PASSENGER'S POWER WINDOW SWITCH REPLACEMENT  ).
      NOTE: After replacing the front passenger's window switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT  ).
      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 0.2 V.
      • Poor ground(G405)
      • An open or high resistance in the ground wire
      26 BRN Ignition switch ON (II), or power mode ON Measure the voltage to ground: There should be at least about 10 V.
      • Faulty front passenger's power window switch
      • A short to ground in the wire
      27 GRY 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 2.5 V 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 2.5 V 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

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
