2015 Stang driver side gives heat. But 2 passenger vents blows cold air?

The controller may be bad. It has to be looked at. Maybe something else, very inexpensive but not at Dana! They are a rip-off. They will try to sell you a wheel alignment first. Use a good local mechanic.

Happened to my 2015 Stang. Dana had to change the actuator. Under warranty

If under warranty go to dana.

Thanks .. still under warranty
