I bought my 4 door Civic about 4 months ago and wasnt really concerned about the ac until it got hot lol. So i put mor refrigerant into it and still nothing. All it does it blow hot air. A guy at work said that it might be the relay, fuse or the pressure switch. But have no clue to where any of those are. My abe my brain is having a huge brain fart but im so lost right now. Can someone please give me a sugestion to see if i can get it cooling agian. Any other info on it please ask and i will do my best at answering. Thanks
