WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. 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. A1 CHECK VOLTAGE TO THE LH FRONT WINDOW CONTROL SWITCH - CIRCUIT CBP47 (GN/BU) 
    • Ignition OFF.
    • Disconnect: LH Front Window Control Switch C504A and C504B.
    • Ignition ON.
    • Measure the voltage between LH front window control switch C504A-2, circuit CBP47 (GN/BU), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to A2  .
    • No:  VERIFY SJB  circuit breaker 47 (30A) is OK. If OK, GO to  A3.

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

  2. A2 CHECK GROUND TO THE LH FRONT WINDOW CONTROL SWITCH - CIRCUIT GD149 (BK/GY) 
    • Ignition OFF.
    • Measure the resistance between LH front window control switch C504B-7, circuit GD149 (BK/GY), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes:  INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
    • No:  REPAIR the circuit. TEST the system for normal operation.
  3. A3 CHECK CIRCUIT CBP47 (GN/BU) FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: SJB  C2280D.
    • Measure the resistance between LH front window control switch C504A-2, circuit CBP47 (GN/BU), harness side and SJB  C2280D-32, circuit CBP47 (GN/BU), harness side.
