Pinpoint Test A: A Single Power Window Is Inoperative - LH Front

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. A1 CHECK THE POWER TO THE LH WINDOW MOTOR 
    • Ignition OFF.
    • Disconnect: LH Front Window Motor C518.
    • Measure the voltage between LH front window motor C518-1, circuit SBB34 (YE/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. Yes  : GO to A2.
    2. No  : VERIFY Battery Junction Box (BJB) fuse 34 (30A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

      If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short.

      REPAIR the circuit. TEST the system for normal operation.

  2. A2 CHECK THE LH FRONT WINDOW MOTOR DELAYED ACCESSORY FEED 
    • Ignition ON.
    • Measure the voltage between LH front window motor C518-3, circuit CBP41 (BU), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. Yes  : GO to A3.
    2. No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  3. A3 CHECK THE LH FRONT WINDOW MOTOR GROUND 
    • Ignition OFF.
    • Measure the resistance between LH front window motor C518-2, circuit GD133 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to A4.
    2. No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  4. A4 CHECK CIRCUIT CPW10 (YE/VT) FOR AN OPEN 
    • Disconnect: LH Front Window Control Switch C504.
    • Measure the resistance between LH front window motor C518-5, circuit CPW10 (YE/VT), harness side and LH front window control switch C504-7, circuit CPW10 (YE/VT), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to A5.
    2. No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  5. A5 CHECK CIRCUIT CPW11 (BU/GY) FOR AN OPEN 
    • Measure the resistance between LH front window motor C518-4, circuit CPW11 (BU/GY), harness side and LH front window control switch C504-2, circuit CPW11 (BU/GY), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to A6.
    2. No  : REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  6. A6 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Carry out the LH front window control switch component test. Refer to appropriate OEM WIRING COMPONENT TESTING for component testing .
    • Did the LH front window control switch pass the component test? 
    1. Yes  : INSTALL a new LH front window motor. REFER to WINDOW REGULATOR MOTOR - FRONT DOOR . INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
    2. No  : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . DE-INITIALIZE then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
