Nissan Altima Problem Report
Nissan Altima AC Not Cold Due to Pressure Hose Leak
The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.
Heat works only when moving and air conditioning blows whatever temperature is outside - mhakim19
A/C not cool. Replaced pressure hose. - Visitor
I had a new engine put in my car in 2010 due to an engine recall and every since my car has not been the same. My air conditioner is blowing hot air I had it serviced but now Nissan is claiming I need to put over $1200 to get new hoses but I refuse to put another penny into this car. I will never purchase another Nissan! - Visitor

The leak was noticed probably 2 years ago, the a/c still works but I figure the compressor may fail as well this is the low pressure hose that leaks, why is there not a recall since it seems to be a common and known problem - Visitor
