My car blows warm air when i turn on the fan and the degree to cold. Then when i turn my a/c on it blows air about the same temperature as the temperature outside of the car. I recently went to a air conditioning shop, they said they only filled a little because it still had some freon in it. Their is no leak either. What can the problem be? Thanks.

 

Compressor clutch might not be engaging, that's about all I can think of if you have freon, no leaks, and the fan is blowing.
