The plug is a safety relief valve for your a/c system - when a system malfunction occurs and the internal pressure escalates it also super-heats the system. The plug is usually lead and melts with high heat - therefore when the system pressure gets too high and the internal temp gets too high, the plug melts and all of your freon blows out. This happened to my BMW one day when it was sitting in the driveway - talk about a shock to the system. The fix was to replace the dryer bottle itself although I don't remember what other pieces were faulty. Then the system was recharged and all has been good ever since.
