I have looked thru the owners manual and did a few searches but did not find an answer. When I have my ac on I noticed that the defrost is always on too. How do I turn off the defrost? This is for my 2018 Mustang GT.

 

I believe your windshield would fog up if the defrost didn't come on when you turn on the ac.

 

It actually fogs with the defrost on because I still ride with the windows open. Anyway, found someone with another Ford of the same year and they showed me how to turn it off. Got it corrected.

 

I experiencing the same issue. How did you fix it?
