Hey guys, my Aircon in my car has been really crap since I bought it because it needed re-gassing. Yesterday I had enough of it blowing just hot air, these days are getting too hot esp with a black car...

so went got it regassed paid $150.... was working soo lovely when I got it back! soo nice and cold no problems. Today was driving along, came to a stop at redlight and heard a loud pop. Thought it was the old bomb of a car in front of me, drove abit and noticed that the aircon felt weak, was blowing hardly any air out.... turned it on maximum and it was still seemed like it was struggling....

I also noticed that when parked in my garage it was dripping water under the car, is that normal ? I don't know if this has anything to do with it but I recently got my heater core replaced because the old one was rooted. Any ideas on what went wrong ? and solutions
