Did you hook up a vacuum pump and remove all the oxygen from the system? If not you will need to have a shop pull a vacuum and refill with the proper amount of freon or get a price for recharging the system here http://repairpal.com/estimator?car_type_id=84 and find a shop here http://repairpal.com/directory?address=38116&car_brand_names=Cadillac
