i recharged the a/c last summer, after buying my car. it worked great and blew cold. this summer it started off fine, but now it doesnt get very cold when its hot outside. when im out for a drive with the a/c on and i pull it back in the garage, alot of water or liquid pools under my car. is it normal to have more than a few drips? i also hear a draining noise from behind the glove box, when i turn the car off. any suggestions on where to check for leaks? any advice would b great. sorry if this has been covered in the past
