I replaced the seals, a/c compressor and got recharged about 2 years ago on my Ford Exsporer. The air blew cold as ice. Unfortunately I had a violent blow out on my front passenger side and the air was on at the time, but ever since I got back in my car a week later the ac hasn't worked! I just replaced the compressor relay and the low pressure switch. Still hot air when you turn on the a/c. And there is no leaks it reads on the meter that refrigerant is at proper levels. I'm getting really frustrated please help!
