2003 Nissan Altima Question: air conditioner is blowing warm air



, 2.5L 4 Cylinder, Walnut, CA, August 27, 2010, 14:21

Before recharging system the air conditioner would blow cool and somtimes warm air and A/C lite would go out when it started to blow warm air. So I recharged the air conditioner on my nissan altima and it blew cold air while system was charging and after driving for 5 min. it started to blow warm air again. I did not see any spots were it could be leaking from and would the low line still have pressure if it were leaking? what are the possible problems?

    Sound like expansion valve is freezing. Make sure the correct amount of freon too much can cause that or the expansion valve is sticking/stuck close.
