Pinpoint Test F: A Single Power Window Is Inoperative - MKZ, RH Front

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. 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. F1 CHECK THE RH FRONT POWER WINDOW OPERATION FROM THE MASTER WINDOW CONTROL SWITCH 
    • Attempt to operate the RH front window using the master window control switch.
    • Does the RH window operate when using the master window control switch? 
    • Yes  : Go to  F7.
    • No  : Go to  F2.
  2. F2 CHECK THE POWER TO THE MASTER WINDOW CONTROL SWITCH 
    • Disconnect: Master Window Control Switch C535A.
    • Ignition ON.
    • Measure the voltage between master window control switch C535A-3, circuit CBP41 (BU), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : Go to  F3.
    • No  : VERIFY Smart Junction Box (SJB) fuse 41 (15A) is OK. If OK, REPAIR the circuit. If not OK, Refer to the SYSTEM WIRING DIAGRAMS article, to identify the possible causes of the circuit short. DE-INITIALIZE, then INITIALIZE the front power window motor. Refer to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  3. F3 CHECK THE VOLTAGE TO THE POWER WINDOW MOTOR 
    • Ignition OFF.
    • Disconnect: RH Front Power Window Motor C623.
    • Measure the voltage between RH front power window motor C623-4, circuit SBP04 (GN/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : Go to  F4.
    • No  : VERIFY SJB fuse 4 (30A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front power window motor.

      If not OK, Refer to the SYSTEM WIRING DIAGRAMS article, to identify the possible causes of the circuit short. Refer to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.

  4. F4 CHECK THE RH FRONT POWER WINDOW MOTOR GROUND CIRCUIT FOR AN OPEN 
    • Measure the resistance between RH front power window motor C623-3, circuit GD139 (BK/YE), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : Go to  F5.
    • No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front power window motor. Refer to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  5. F5 CHECK THE MASTER WINDOW CONTROL SWITCH-TO-RH FRONT POWER WINDOW MOTOR CIRCUITS FOR AN OPEN 
    • Measure the resistance between RH front window power window motor C623-1, circuit CPW12 (GN/OG), harness side and master window control switch C535A-2, circuit CPW12 (GN/OG), harness side.

    • Are the resistances less than 5 ohms? 
    • Yes  : Go to  F6.
    • No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the RH front power window motor. Refer to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  6. F6 CHECK THE MASTER WINDOW CONTROL SWITCH 
  7. F7 CHECK FOR VOLTAGE TO THE RH FRONT WINDOW CONTROL SWITCH 
    • Disconnect: RH Front Window Control Switch C624.
    • Ignition ON.
    • Measure the voltage between RH front window control switch C624-2, circuit CBP41 (BU), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : Go to  F8.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  8. F8 CHECK THE MASTER WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: Master Window Control Switch C535A.
    • Measure the resistance between master window control switch C535A-2, circuit CPW12 (GN/OG), harness side and RH front window control switch C624-5, circuit CPW12 (GN/OG), harness side.
