Now the auxiliary fan spins at high speed at the setpoint of 17 bar and turns off at 13 bar, but at this time with the outside temp at 95 C, air still does not cool. So basically, I need to find out why the auxiliary fan does not stay on when AC is on. It seems that the refrigerant pressure is okay. I really want to isolate this problem without having to take it to the dealer.

Did C43's come with fan control module? Some people are saying that it could be the problem
