Hi all,

For some reason my AC unit doesn't seem to want to blow out cold air!! All switches/buttons are on and set to "Lo" setting, AC button is on, tried various combinations with Mac AC. But it doesn't seem to be getting cooler in the car. With the heat from the exhaust and the outside temperature...it actually very uncomfortable to drive!!

Here is a twist:
The left vents (closet to the wheel) blow out warmer air then the rest ...!?! It's a noticeable difference in temperature...I have no explanation!?

It's a 2016 mustang GT... is this a common fault with the AC units in this car?

What could it be?

There is a TSB regarding the air conditioner that affects your Mustang. The best course of action is to take it into the dealership and let them fix it.

Its likely the evaporator core. A common failing on early S550s. I believe they now have a revised evaporator so if the dealer changes it, ensure they use one of the latest design, or you may find the problem again in the future!
