Service 4WD system 2020 Ram 1500

[Oscar1500]

Hello everyone,
I’m in need of some help and will probably take it to the dealership, but some context I purchased the truck used and have took it to the dealership to get the oil serviced. OBD II test was done and nothing came on. The issue today is that I turned on my 4WD High and the service system light came on but at the same time the A/C started blowing hotter even when it was put at 65 degrees. Any recommendations or tips in what it could be?
-Actuator
-electrical relay issue
-sensors that engage the 4WD
That’s all I can think of.

Hope someone here might know what it could be. Thanks in advance.

There have been posts about the front axle actuator troubles. Try a search, should come back with some hits.
Did the system actually engage?
You must be somewhere way down south to be running A/C. For that to mess up, not sure.
