HVAC cooling is very erratic after last update. Cools fine (freon level must be OK), but if you adjust the temperature on drivers or passenger side by 1-3 degrees the R1T blows hot air and does not stop blowing hot air until you turn HVAC off and on. What is strange is the HVAC screen indicates the system is cooling (Blue) when hot air is blowing out of the vents. Example: Outside temp 75, Driver and passenger set to 71, passenger changes temp to 73. Hot air starts coming out of passenger vents. So much hot air the cabin heats up very fast. Only way to fix is turn HVAC off and on. Had it in for service and all they did was check for error codes and found none. They did not check freon level and only did a 10 minute test drive. System worked fine after picking the truck up after service. Drove it about 180 highway miles back home and it started doing it after we were in city traffic and the wife changed the temperature. Note: I do not use Auto mode, fan speed set to 2, no recirculation. System seems to change to recirculation on its own and the fan speed seems to change (higher) even though I did not change it. No rhyme or reason. Maybe I just have to wait for the next update in hopes it fixes it.
