2017 F250 Heat Turning on by itself

The heat in my 2017 F350 recently started turning it on all by itself. I keep turning it off but it sporadically turns on again. Does anyone know what is causing this? or better yet what the fix is?

Do you have your climate set to auto?

Additional trim info on your truck would be most helpful.

The truck is telling you it’s cold.

No, when I turn it completely off it still just randomly turns back on as if I turned the ****.

It does have the problematic temp sensor in the evap core that could be failing. This vid is for f150, but same for F250
