As of yesterday I have lost the ability to control my fam speed for the HVAC system in my 2014 fiesta st, although auto seems to work, as long as temperature.
About the fan knob itself, the HVAC controller knows what setting I'm putting it to as the lcd displays what level the fans should be at but will not adjust it.
I tried resetting the system, turning the controller on and off, turning the car on and off and turning auto on and off and the fans are just at full blast at all times.
Temperature and a/c controls all seem to be normal.
Anyone come across this at all?
Edit: I can also select where the air comes out of still. On the surface everything seems normal with just no fan speed adjustment
