Hi, my 2004 Mazda3 is having an air conditioner issue. The driver side air vents blow hot air, but the passenger side air vents blow cool air (not as cool as I think it should be, just cooler than the hot side.) We had issues with it last summer that were repaired and freon was added at that time. I would be grateful for any input. Thanks in advance!
You need to have it repaired again.
I don’t know who repaired it and added refrigerant (it’s not freon) last time, but you’re going to have to go back to that person or find someone else. Your choice.
I suggest a shop that specializes in automotive HVAC systems. They can usually fix whatever might be wrong.
It sounds like you may have more than one problem with your car’s AC system.
