Exclamation AC problems please help

My AC doesn't blow cold air. .. . I have had the system recharged and the local ran a leak test.*That part checked out. My problem is that it still blows hot air. Are there any suggestions as to what might be causing this. I have read that the next thing to do would be to see if the*AC*fuse*is blown or check the relay. Where would these be located? I am praying it is one of these or something that is cheap. I am not set on cheap being the answer necessarily I just want to know what I should and how to do it

if it has been checked for leaks and has been recharged then the a/c compressor has to be working or the recharge wasnt done correctly , if the compressor didnt cycle on the system wouldnt have taken in freon , first thing is to check and see if the compressor is coming on, if not then see if there is power to the low pressure switch at the accumulator

there are lots of things to check , if power to low pressure switch and a/c is cycling on , then see if line is cold goin in to dash , if so id guess blend door actuator has quit working and is stuck on heat

just a couple things to start to look at
