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

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 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 LH FRONT WINDOW CONTROL SWITCH OPERATION 
    • Attempt to operate the RH window using the LH front power window control switch.
    • Does the RH window operate when using the LH front power window control switch? 
    • Yes:  GO to  F7.
    • No:  GO to  F2.
  2. F2 CHECK THE POWER TO THE LH FRONT WINDOW CONTROL SWITCH 
    • Disconnect: LH Front Window Control Switch C535A.
    • Ignition ON.
    • Measure the voltage between LH front 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 appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. DE-INITIALIZE, then INITIALIZE the front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  3. F3 CHECK THE POWER TO THE WINDOW MOTOR 
    • Ignition OFF.
    • Disconnect: RH Front Window Motor C623.
    • Measure the voltage between RH front 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 window motor.

      If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

  4. F4 CHECK THE RH FRONT WINDOW MOTOR GROUND 
    • Measure the resistance between RH front 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 window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  5. F5 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW MOTOR FEEDS 
    • Measure the resistance between RH front window motor C623-1, circuit CPW12 (GN/OG), harness side and LH front 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 window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  6. F6 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
  7. F7 CHECK CIRCUIT CBP02 (GN) FOR VOLTAGE 
    • 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 LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS 
    • Ignition OFF.
    • Disconnect: LH Front Window Control Switch C535A.
    • Measure the resistance between RH front window control switch C624-5, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.
