My car is only blowing hot air, compressor works fine but always hot. Put Freon in and that worked for about two weeks and hot again. Had it inspected and they said they could not find any leaks. Please help.

Is the compressor clicking on and off ?

yes it is firebird338...it blows really strong air but is very hot...

Because like Kelly said if you had freon put in system and it worked for two weeks and its hot again it has to be a leak now if you said the system is full and still blowing hot air that is a different story.

Leak must be in the evaporator in the vehicle where you can not see.

But its weird, I had it to a shop and they ran some liquid through it and could not find any leaks at all. So how do I test the evaporator?

I am going to recommend something that I used before and it worked great. R134a refrigerant stop leak put some in a friends vehicle last summer and I talked to him just the other day and its still cold.

To get to the evaporator you have to take underneath the dash out the heater / A.C box.
