WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 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? 
    1. YES  : Go to  E6.
    2. NO  : Go to  E2.
  2. E2 CHECK THE POWER TO THE WINDOW MOTOR 
    • Key in OFF position.
    • Disconnect: RH Front Window Motor C623

    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  E5.
    2. 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. E5 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Carry out the Master Window Adjust Switch Component Test. Refer to COMPONENT TESTING .
    • Did the window control switch pass the component test? 
    1. YES  : INSTALL a new RH front window motor. REFER to Glass, Frames and Mechanisms - Exploded View, Front Door  and Window Regulator and Motor - Front Door . INITIALIZE the RH 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 . INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

    • Disconnect: RH Front Window Control Switch C604
    • Key in ON position.
      • Fig 6: Checking Circuit CBP02 (GN) For Voltage
      GF0028364Courtesy of FORD MOTOR CO.
    • Measure the voltage between RH front window control switch C604-2, circuit CBP02 (GN), harness side and ground.
    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  E7.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  7. E7 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS
