Some 2014-2018 Fiesta vehicles may exhibit a clicking noise from the driver side dash panel while operating the air distribution control. This may be due to a damaged door actuator and/or contact between the instrument panel (IP) ground and/or Sync 3 radio harnesses and the air distribution door actuating gear. To correct the condition, follow the Service Procedure steps to reroute the wiring harnesses and/or replace the door actuator.
