Nothing has gone wrong. Heater and A/C vent on dash board is loose
The car's A/C sucks. Even brand new it still doesn't cool good, the worst part about that whole thing is that with the a/c on the car is powerless. Overall though the car is great, I have really enjoyed it.
Personally my car will freeze a snowman... I LOVE the A/C unit in my car... did you ever have your car checked of leaks or recharged?
