There must be an refrigerant leak somewhere in the A/C system. First, you have to recover what's in the A/C system, and check how much is lost. Usually, on that car, it takes about 2.2 lbs. of R134-a refrigerant. After you've determined that you're low on refrigerant. Vacuum the system for a good 30 minutes (Minimum), and recharge the system with 2.2 lbs. of R134-a refrigerant. Time consuming and must have an A/C machine to do all of this. Last, inject florescent dye with PAG oil in the A/C system to pinpoint your leak if you have any.
