CCCP1999

My A/C was being freaky on the way home today. It is blowing cool on the pass side and warm on the driver side. Anyone have this happen before? This is a 2015 GT Prem.

Probably a bad blend door actuator.

I guess it's off to the dealer.

Do you know if your car has seperate ac controls for drivers and passenger side? Some new vehicles have these. If your car does, it could simply be that.

It does. But i never touched anything to change it. And i tried everything on the way home and nothing worked.

I'm not familiar with anything newer than 05, I'd suggest waiting for someone to chime in that has more knowledge of a newer mustang. I had an issue similar to this on my 02 svt lightning and it was the blend door actuator but it doesn't have seperate ac controls for passenger and drivers side.

I had some kind of gear like that in my 2010 5.3 Colorado where the heat got stuck open.

Yep, the blend door actuator has an electric motor/gear in it. The motor goes bad.

Take it in. My evaporator was just replaced.
