Odd happening after shut off
Randomly, after I shut the truck down I will go back out to the garage and it will be "on." A humming noise that quits when I open a door. Could this be the rest function for the A/C? Even in winter? Did it yesterday and it is 20 outside but 50 in the garage?
2nd question - the rear end was down the other morning after sitting for maybe 4 days. This is not normal, correct?

2 is not normal. You have a leak in the back. Change both air bags for good measure. Check the rear levelling rods too

If you have had an ac software update it will run longer and more often because owners were complaing of the moldy smell from the ac system.
This was caused by dampness in the cabin filter which they tried to fix by running the ac rest feature to try to dry it out.
The best thing to counteract the moldy smell ever from coming is just to change the cabin filter yearly and opting for the mann ferocious plus filter that filters bacteria mold and nearly all allergens too. Thats the best one and really easy to diy
