95 Nissan Altima A/C Problem

Hello-I have a problem with my a/c.When I first start the car the a/c will blow cold for only about 5 minutes or until the car heats up,then the air blows very warm.If the car has been driven and I turn it on it will only blow warm.Only when the engine has been sitting a while will it blow cold,then like I said it goes to very warm.I live in florida and it is so hot right now:frown: ! If anybody has any suggestions I would greatly appreciate it!Thanks alot!

Do you have a full charge of refrigerant?

I live in FL too, and this summer heat is no joke. But you need to take the car to a mechanic so they can check to make sure your a/c system is fully charged with refrigerant and that there are no leaks either. My a/c system, back when i bought the car, was completely shot and had to have the entire thing rebuilt, $900.00... ouch. But yours sounds like the refrigerant needs to be replaced/recharged. Until then do not use the a/c as it can be damaging very expensive parts in the system.
