Hey everyone. So ive got a 2016 mk7 ford fiesta st. The blowing system in the car is broken. Im not entirely sure what's wrong, but i can't direct the blowers anywhere but through the main ones on the dash. This is causing massive issues when my windscreen is getting fogged up and I cant clear it. The blower works fine when I select between 1 through 4, but i can't direct it anywhere. I was on a long drive the other day and the onscreen dash overheated and shut itself off. My suspicion is there's a broken connection somewhere which has caused the heat to blow over the electrics and overheat. Anyone know how to diagnose/fix? Thanks !!

There's a blend door actuator thread here that covers the locations, function and part numbers for all three.

I'm not sure whether you're left-hand drive or right-hand drive there.
The Dorman brand part has been reliable.

Appreciate your reply. Im right hand drive in this country. Everywhere ive read has said that when the actuator goes, you'll hear a strange noise from the dash. I dont have that noise, just unable to direct the blower. Could this still be the same issue? Sorry I don't have a vast array of car knowledge !!
