If anyone with a factory dual zone climate control can get me some logs like the ones i posted above, that would be a big help.
A thread on hdrams.com has people describing the same problems with their FACTORY dual zone climate control that i'm having with my retrofit. Their ATC is always running a little hot, and they can't get cool air out of it until they push it to LO.
I'm having the same issue, when the temperature outside is below 60, and i have the temperature set to 70, it'll set the blower speed to 1 and blow luke warm air, but eventually it still gets too warm, so as i turn the temperature down to say, 68, the blower speed increases, and changes the output to the dash vents, but it start blowing WARMER air. So i turn the temperature down to 64, blower speed increases, and the air it's blowing gets even HOTTER. It's not until i force the temperature to LO that i actually start to get cool air.
And this behavior makes sense based on the log data I posted above, as i turn the set temperature on the Uconnect Down, the truck is seeing that value as the in cabin air temperature, so instead of the truck seeing that I want cooler air, it's seeing the cabin is colder, so it throws more heat at me.
I suspect when the weather here switches to hot summer weather where it's 80+ most days, I may have the opposite problem, where it's always making it too cool in the truck and as i turn the temp up it's going to continue throwing COLDER air at me, thinking the temperature in the cab is rising.
