If there are no leaks it should last indefinitely. I would recommend calling your local dealer and having them check for recalls. There is a large recall on one of the ac lines under the hood.
v have to check the blower motor,ac pipe lines and cluster assembly
check for leaks, mostly check toward the rear and lines.
take it to a shop that recharges ac and get them to charge it and check for any leaks in the system. probably be about 80$
Check both the heater core as well as the heater hoses for leaks...........
Things to check: Coolant level Heat and AC fuses Vacume leaks Actual operating tempurature of the engine.
Check your fuel cap or gas tank for leaks, or maybe the gas lines.
