I noticed last week when I have the HVAC on the floor only setting, I still get air flow out of the defrost vent. Enough to wonder why my face getting hot when I was only trying to warm my feet. I reported this to the service tech when I dropped the truck off for some recalls and other warranty service. When I picked it up yesterday the paperwork noted that they "relearned A/C housing door actuators". I didn't think to check it on the way home last night but checked it today and nothing has changed. Still air flow from the defrost vent when on the floor only setting. Has anyone else noticed this with theirs? Guess I'm curious if this is "normal" or if I should make an issue of it.
