Hvac wont come back on automatically

[Frank Pileggi]

Have a 2016 Ram 1500 with scat pack 1 kit on it. Diablo tuner and pedal commander. Needed to replace battery two months ago. Since then the hvac works fine, but it doesnt remember settings once i shut off truck. I have to manually press buttons to turn on again and reset setting/ temp.
Took to dealer, they replaced uconnect, hvac controls, and its still doing it. Dealership has had my truck for 16 days so far with no luck.

Anyone experience this with your truck

Likely the HVAC module. I’m assuming you have the bigger RA3/4 radio. Depending on which HVAC system you have the HVAC module is separate from the controls. It is located behind the glove box.

Curious what the resolution was...I just recently had the same issue and replacing the AC Control Unit (the center stack) resolved the issue.
