The fan does ramp up speed as the temp rises, I'm not sure about the shutters, they may just open up completely anytime the fan is on. The AC condenser is also behind the shutters and I think their late opening effects the ac temps very negatively.
Does anyone know of a tuner or reprogramming that can adjust when the cooling fan and grill shutters come on? I want to lower the temp as the factory setting is pretty high IMO. 5th gen 2020 1500DT
