WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Q1 CHECK REAR PASSENGER WINDOW OPERATION FROM THE LH FRONT WINDOW CONTROL SWITCH 
    • Ignition ON.
    • NOTE: Make sure the LH window control switch lockout switch is in the UNLOCK position.

      Attempt to operate the rear passenger windows from the LH front window control switch.

    Do the rear passenger windows operate from the LH front window control switch? 

    • Yes  : GO to Q2  .
    • No  : For Base, REPAIR circuit CBP01 (BU) for an open.

      For XLT or Limited, GO to  Q3.

    • Disconnect: LH Front Window Control Switch C504  (XLT, Limited) or C535A  (Base).
    • Disconnect: LH Rear Window Control Switch C701  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C701-5  OHM (XLT, Limited) or (Base) C535A-3 

    Is the resistance less than 3 ohms? 

    • Yes  : INSTALL a new LH front window control switch. Refer to WINDOW CONTROL SWITCH .
