When I turn my manual climate control temperature control **** all the way to the left it has a spring loaded extra little bit of a turn. What is supposed to happen whenI do this? Is it supposed to turn on the Mac a/c light along with a/c button light, recirc button light and face air button light? When I turn it to the left I do not get the Max a/c light nor does it turn on the rest of the functions. If the power is off to the climate control kt will only turn it on to the last setting. I would appreciate any help on how this system should work i am new to F150s. Thanks so much.

I do not have a “Max A/C” that I am aware of. There is a Max a/c light in the center of the temp ****. But it never lights up. I am aware of the manual tips and suggestions as well.

Thanks. I understand that’s what the manual says but since mine isn’t doing that I wanted to know how it really did work in the “real” world. Mine is a 2015 XLT as well. I will have to check on what’s happening then. I think maybe the gear inside the control could be a tooth off or something. I got a 4” to 8” conversion kit and took the heated seat buttons out. Probably missed it by a tooth or something.

So. If anyone knows the way you might calibrate the temp control **** on a 2015 xlt with manual climate control it would be greatly appreciated. If not I will start experimenting.
