I have a 2019 that is having an issue with the climate controls. The system only blows air at full heat. Fan speed works on all levels, but regardless of what the temperature is set at it only comes out HOT.

When changing the temperature I have to use the digital slider to drop the temp on the screen (not that it blows any cooler). As soon as I use the up arrow the screen immediately jumps to read HI… it does not go up intermittently.

Has anyone seen this issue?

Does the head unit actually control the climate control system?

attached is a pic of the dash set up.
Any assistance would be appreciated.
