Pinpoint Test C: A Single Power Window Is Inoperative - Rear Quarter

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.
NOTE: If BCM-B on-demand DTC B126D:15 or B1269:11 is present, the rear quarter windows may still function during convertible top operation, but will not function when commanded by the window control switch. Refer to the Body Control Module B (BCM-B) DTC Chart  for diagnosis.

    1. Yes  : GO to C6.
    2. No  : VERIFY Smart Junction Box (SJB) fuse 1 (30A) and 4 (30A) are OK. If OK, REPAIR the circuit. 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.

  6. C6 CHECK THE REAR WINDOW MOTOR DELAYED ACCESSORY FEED 
    • Ignition ON.
    • For an inoperative LH rear window, measure the voltage between rear window motor C3118-3, circuit CBP41 (BU), harness side and ground.
    • For an inoperative RH rear window, measure the voltage between rear window motor, C3119-3, circuit CBP41 (BU), harness side and ground.
