Front Passenger's Power Window Switch Input Test

2008 Acura RDXSECTION Front Passenger's Power Window Switch Input Test
NOTE: The power window control unit is built into the front passenger's power window switch.
  1. Remove the front passenger's power window switch (A) (see FRONT PASSENGER'S ).

  2. Reconnect the front passenger's door wire harness to the front passenger's door sub harness.
  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, make the following input tests at the connector.
      • If a test indicates a problem, find and correct the cause, then recheck the system.
      • If all the input tests prove OK, the front passenger's power window switch must be faulty; replace it.
  4. With the switch 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 CHART

    Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
    3 PUR Under all conditions Check for continuity between the No. 3 terminal and No. 2 terminal of the power window master switch 22P connector:
    There should be continuity.    		 An open in the wire
    14 RED Connect the No. 14 and the No. 7 terminals and No. 8 and No. 1 terminals momentarily with jumper wires Check front passenger's power window motor operation:
    The window should go down.
    • Blown No. 30 (20 A) fuse in the under-dash fuse/relay box
    • Faulty front passenger's power window motor
    • An open in the wire
    • Poor ground (G505)
    8 YEL Connect the No. 8 and the No. 7 terminals and No. 14 and No. 1 terminals momentarily with jumper wires Check front passenger's power window motor operation:
    The window should go up.
  5. Reconnect the 14P connector to the front passenger's power window switch. Turn the ignition switch 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, the control unit must be faulty; replace the front passenger's power window switch.
    SYMPTOM CHART

    Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
    7 GRN Under all conditions Measure the voltage to ground:
    There should be battery voltage.
    • Blown No. 30 (20 A) fuse in the under-dash fuse/relay box
    • An open in the wire
    1 BLK Under all conditions Measure the voltage to ground:
    There should be less than 0.5 V.
    • Poor ground (G505)
    • An open in the wire
    2 BLK Under all conditions Measure the voltage to ground:
    There should be less than 0.5 V.
    • Poor ground (G505)
    • An open in the wire
    6 RED Ignition switch ON (II) Measure the voltage to ground:
    There should be battery voltage.    		 A short to ground in the wire
    5 BLU Ignition switch ON (II), and front passenger's power window switch moving up or down Measure the voltage between the No. 5 and No. 6 terminals:
    There should be 0 V-about 5 V-0 V-about 5 V repeatedly (a digital voltmeter should read about 2.5 V while the window moves).
    • Faulty front passenger's power window motor
    • An open in the wire
    • A short to ground in the wire
    4 YEL Ignition switch ON (II), and front passenger's power window switch moving up or down Measure the voltage between the No. 4 and No. 6 terminals:
    There should be 0 V-about 5 V-0 V-about 5 V repeatedly (a digital voltmeter should read about 2.5 V while the window moves).
  6. Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).

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.
