Hi all. I apologize in advance if I am posting something which has already been treated but I cannot fine online any answer to my problem:
I own an Xterra 2010 SE OFF Road model. The issue is the following: after having discovered a leakage at my AC system due to a crack at my condenser, I decided to change it. I have been at the mechanic who replaced the condenser and filled the gas. The system was working very well, getting cold like never before.He also checked for other leakages and for the compressor to engage and everything was working fine. After a couple of days I went for a long off road track which was very slow( max car speed 20km/h) and the ac suddenly started to blow warm and then hot air. So I opened my bonnet and check manually the temperature of the hi-pressure pipe and it was extremely hot, rather than extremely cold. I tried to cool down the system spraying some cold water on the condenser and it worked. What I can realize now is that if I m stuck in the traffic or stopped at any traffic light the ac blows warm air . As soon as I speed up the air becomes cooler,but it never reaches an optimum level, like when the car came out from the workshop.
Does anybody have an idea of what the problem could be?
I live in the middle east and at the moment the temperature is 47 degrees Celsius, so the AC is crucial. It is also crucial to find a possible cause of the problem in this part of the world, otherwise if u let the mechanic find it for you, you will loose money and your mental health.
I do appreciate any comment in advance.
