The problem: Water can intrude into the module and connector and cause wiring corrosion/ damage and shorts in the electrical system.
The results, according to the OEM, could include things like rapid turn signal flashing, loss of the instrument cluster display, loss of heater and air conditioning controls, and loss of multimedia including radio, screens and SYNC system.
More seriously, prolonged water intrusion could cause an electrical short that could lead to seat belt pretensioner deployment, "a burning smell" and/or risk of fire, Ford explained. The problems could occur even when the vehicles are parked and the ignition is off, the company noted.
The fix: Dealers will add a drainage hole to the driver's door stepwell, according to Ford, and incorporate a fuse into the vehicle wiring harness at no charge; parts are available now to complete the repairs.
The Ford reference number for the recall is 17S34.
