[QUOTE="K223, post: 1503039, member: 36701"] Makes sense now. Since it’s been an ambient temp of 95 or close to it and take into account the sun heating up the shell of the truck. It’s showing an ambient of 108-114 during the day. That’s surely what’s turning the fans up to full upon startup. At night the fans were at a normal slow speed. While I can see the truck taking one input and going to maximum cooling, on a cold start. The coolant temp and AC system can’t possibly be that high to warrant it. But I won’t pretend to have engineered them truck and the reasoning behind it. 114 registering at the AAT is of concern in the grand scheme of things in remaining cool. While on the fan subject, what’s the strategy that controls the IC fans? [/QUOTE]
