This just happened suddenly after I switched it to to the windshield vent/heater and when I tried to switch it back, it’s been wonky since. I set it to blow directly to my face and it’s weak, but also my feet and the windshield vent are receiving air as well. Is there a quick fix to this or do/should I bring my car to the dealership?
First step for this is replacing cabin air filter if you've not done so in a while... Second step is taking some time to exercise all the settings to see if they will stay unstuck... After that there's plenty of things to try under the dash, but hopefully it doesn't come to that.
