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 !!
