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

    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!
