So i bought the car 6 months ago never really used AC since it wasnt warm enough but when i tried to turn it on the other day turned out its not blowing cold air. went to re-gas it  the machine they were using showd there is 55 grams of old gas in, pumped out, put new gas in and oil i was watching it do it no errors but when i turn aircon now the air seems cold but i think its only outside cold its not AC...is there anything that would stop it? it was topped up an hour ago.

Failed compressor?  Common problem.

is that the only thing that would have failed? is it expensive to fix? is it something i can do myself or i have to get a specialist to fit it?
