08 Mazda3 4 cylinder 5sp w/ AC problems
 

HELP PLEASE
Ok so I’ve recharged my AC and it still was full from before. I’ve talked to people about it some say it could be a relay or the actual compressor. It blows but hot idk what to do if it’s a relay which one should I check a compressor is pretty high so I don’t wanna fork out the money for it if I don’t need it so any advice would be greatly appreciated. My dad had it I bought from him he said 2 years ago they spend $1100 bucks to fix it so I’m hoping it should be simple. It’s my work car and it’s freaking hot down here in Texas and it’s extremely hot I’ve got to get it fixed ASAP
