Ford SYNC with MyFord Touch Radio Won’t Turn Off in a 2014 Ford Fiesta SE

On Thursday, 21 June 2018, the radio in my 2014 Ford Fiesta SE would not turn off. (For identification purposes, my car has a Ford SYNC with MyFord Touch radio.) I also couldn’t turn down the volume using the volume knob on the dash or the volume buttons on the left side of the steering wheel. I knew removing the negative battery cable would reset the radio and solve the problem, but so would removing the radio’s fuse, which would be easier.

I chose the latter.

The owner’s manual indicates that there are two fuse boxes: One underneath the hood on the driver side, and one behind the glove box on the passenger side. The radio-based fuses are in the fuse box located behind the glove box.

Fuse 10 (15A), marked F10, is the fuse for an “Audio unit, SYNC” radio, while fuse 24 (7.5A), marked F24, is the fuse for an “Audio unit.” Because I have a SYNC-based radio, F24 is rightfully missing; F10 appears in the top right group of fuses. (See below.)

With the car off and the key extracted from the ignition switch, I removed F10, waited five seconds, then replaced the fuse.

It’s been five days since this occurred and the problem has not resurfaced.

Update (9 August 2018)

Radio is still working fine.
