Hi
As the title suggests, I am having AC issues with my Passo at idle speed, no issues while driving at a constant speed, one AC wala said its a PAIDAISHI problem in Passo while the other one said AC is fine just get your radiator & thermostat checked, but I am still facing the same issues after radiator service.
any remedies/suggestions would be of great help as I am getting pissed off day by day
BTW it's 2007 1.3 Model.
Also suggest me some good Engine oil or it as well 
JazakALLAH
