A/C Temp Control

[Mcontrols]

Anyone know how to calibrate the digital AC temp control. When it's cool in the morning, 65 or less outside, I have to turn the set point down, controls set to Auto, to 68 to get the fan to ramp up from lowest speed. I have the reverse when it's warm outside, 75 and above, have to run set point to 78 to get the fan to slow from med high or the car feels like Antarctica. My Tahoe would just stay set on 74 and maintain it no matter how hot or cold it was outside. Anyone else have this issue?

Ok, I'll update my own thread. I was not waiting long enough for the system to find set point. My Prius and Tahoe have much faster acting controls but I left alone my FX settles in in about 5 minutes.
