yea same problem here 04 grand prix gtp. ac leaks out couple of seconds after u put in somewhere on front drivers side under the fans by the air cleaner and the receiver dryer freon riseing up like steam. im thinking just replace receiver dryer or the ac hose assembly. any ideals is the connection ever loose and just needs to b tightned or maybe something simple like new orings ? if the leak is that big where u see it riseing up like steam would u still pinpoint with the dye and how many cans of dye to use. wanna do my self will post pictures /video if can do work myself
