AC Not Cold Due to Pressure Hose Leak on Nissan Altima

Problem Description and Possible Solution

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
A/C not cool. Replaced pressure hose.
the ac just stopped blowing cold air
A/C blowing outside temp, not cold anymore.
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!
Ac problem, hat air
replaced pressure hose...$400
Looks like a tiny pin prick hole near the crimped area.
Ac blowing hot air!
A/C Low pressure line leaking. Estimate cost to fix 350
Both hoses are leaking...
Leak detected at front connection using blacklight detection.
At the shop, dreading the bill. Nissan should have issued the recall, over 200 exact issues in two years according to a friend that worked in a local dealership's service department. #stilllovemynissan
