Not having this issue...when its hot inside the fan kicks in high...too loud really.
My wife complains constantly about the fan running too high when the truck is trying to cool down. Typically have to adjust the temperature up a degree or two to slow the fan speed down, even when my fan speed control is set to the lowest setting on the MYLINK screen.
I normally find the biggest issue with my auto mode when the set temperature is too close to the outside temperature. This morning the outside temperature was 71 degree, I had to turn the set temp down to 68 degrees to make myself comfortable. It it was 81 deg outside, the fan would likely be blowing like a cyclone with a setpoint of 68 deg.
