I have a 2012 nissan juke. My AC system does not cool the car if the car is on idle or if it is operating at lower speeds/lower RPM's. When the car speeds up to high city/highway speeds it kicks in and definitely works. At first i was told it could be the cooling fan control module or the fan shroud. I changed both and still the same issue. I checked the AC freon and its working perfectly. Any ideas or suggestions?

You need to have AC pressure gauges hooked up while engine is running to verify compressor is outputting correct pressures.

Also you need to verify proper radiator fan speed operation when engine is running. The Nissan Consult 3+ scan tool can operate the fan at all speeds to verify this.

Another thing that can affect AC performance is a restricted AC condensor, amount of refrigerant charge, and weak alternator output.


So unless you have all the tools to test all that you need to take it to an AC shop or Nissan Dealer.
