My A/C had been blowing hot and cold for months and finally it started blowing just hot air. Also the tempature gauge in the car keeps running a little hotter than normal when the A/C was acting up and the car was in drive. What exactly could be the problem.

Hi there,

Thank you for the donation,

the first thing that you need to do is check that the compressor is turning with the air on, if not you should then be checking the system for any refrigerant leaks, as if the system is low, this will cut the power to the comp and shut the system down, start here.
