So once my car is driven for a while my A/C comes on full blast. So I just end up turning the A/C on, but at the lowest level. Sometimes it goes off if I put it on Auto.

?Sounds like a overheating problem in the near future...

 

Nothing to do with overheating. Are there any codes being reported by the OBD2? Could be the control box under the radio, or even just a loose connection in one of the ribbon wires on that control box, or a bad selector switch. Check for fault codes first, as that's the simplest.
