Pinpoint Test C : A Single Power Window Is Inoperative - RF, Navigator

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

  1. C1 CHECK THE MASTER WINDOW CONTROL SWITCH OPERATION

    • Attempt to operate the RH window using the master window control switch.

    Does the RH window operate when using the master window control switch? 

    Yes  GO to  C7.
    No  GO to  C2.

  2. C2 CHECK THE POWER TO THE WINDOW MOTOR

    • Ignition OFF.
    • Disconnect: RF Window Power Window Motor C646.
    • Measure the voltage between RF power window motor C646-3 , circuit SBP04 (GN/RD), harness side and ground.

    Is the voltage greater than 11 volts? 

    Yes  GO to  C3.
    No  VERIFY the BCM fuse 3 (30A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation. If not OK, REFER to the OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short. REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

  3. C3 CHECK THE RF WINDOW MOTOR DELAYED ACCESSORY FEED

    • Ignition ON.
    • Measure the voltage between RF power window motor C646-2 , circuit CBP41 (BU), harness side and ground.
    1. GFD137645Courtesy of FORD MOTOR COMPANY

    Is the voltage greater than 11 volts? 

    Yes  GO to  C4.
    No  VERIFY BCM fuse 32 (15A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation. If not OK, REFER to the OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short. REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

  4. C4 CHECK THE RF MOTOR GROUND

    • Ignition OFF.
    • Measure the resistance between RF power window motor C646-8 , circuit GD138 (BK/WH), harness side and ground.
    1. GFD137646Courtesy of FORD MOTOR COMPANY

    Is the resistance less than 3 ohms? 

    Yes  GO to  C5.
    No  REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

  5. C5 CHECK THE FRONT WINDOW SWITCH TO RF MOTOR FEEDS

    • Disconnect: Master Window Control Switch C535A.
    • Measure the resistance between RF power window motor C646, harness side and master window control switch C535A, harness side using the following chart:
      RF Power Window Motor Circuit Master Window Control Switch
      C646-7 CPW20 (WH/OG) C535A-5
      C646-4 CPW19 (VT) C535A-2
      C646-6 CPW31 (GN/WH) C535A-1
    1. GFD137658Courtesy of FORD MOTOR COMPANY

    Are the resistances less than 3 ohms? 

    Yes  GO to  C6.
    No  REPAIR the affected circuit. DE-INITIALIZE, then INITIALIZE the RF power window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

  6. C6 CHECK THE MASTER WINDOW CONTROL SWITCH

    • Carry out the master window control switch component test. Refer to Component Testing .

    Did the master window control switch pass the component test? 

    Yes  INSTALL a new RF power window motor. REFER to Window Regulator Motor - Front Door . INITIALIZE the RF door window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
    No  INSTALL a new master window control switch. REFER to Window Control Switch . TEST the system for normal operation.

  7. C7 CHECK CIRCUIT CBP32 (GN/VT) FOR AN OPEN

    • Disconnect: Passenger Window Control Switch C643.
    • Ignition ON.
    • Measure the voltage between passenger window control switch C643-2 , circuit CBP32 (GN/VT), harness side and ground.
    1. GFD137659Courtesy of FORD MOTOR COMPANY

    Is the voltage greater than 11 volts? 

    Yes  GO to  C8.
    No  REPAIR the circuit. TEST the system for normal operation.

  8. C8 CHECK THE FRONT WINDOW SWITCH TO RF MOTOR FEEDS

    • Ignition OFF.
    • Disconnect: RF Window Power Window Motor C646.
    • Measure the resistance between RF power window motor, harness side and passenger window control switch, harness side using the following chart:
      Passenger Window Control Switch Circuit RF Power Window Motor
      C643-3 CPW20 (WH/OG) C646-7
      C643-5 CPW19 (VT) C646-4
      C643-4 CPW31 (GN/WH) C646-6
    1. GFD137660Courtesy of FORD MOTOR COMPANY

    Is the resistance less than 3 ohms on all circuits?
