Another classic case of why you should not attempt to work on your A/C when you don't know what you are doing. Rarely, recharging with one of those DIY kits will fix the problem. Take your car to a shop and have them hook up the right equipment to diagnose the problem. In the long run, you will spend less time and money that way than trying to save by DIY.
