      I have a 2020 Silverado Trail Boss. When the AC is on, there are times when the fan switches automatically to recirculation mode even though the button is not illuminated for recirculation. Auto is also not turned ON. At times recirculation will turn back off on its own, other times have I have to press the recirculation button to turn it ON and then press it a second time to turn it back off. There have been times even after pressing the button twice to turn it back off, it will switch automatically on its own. If the AC is not ON, this never happens, it only happens when AC is ON.

      Any tips for this or is a GM programming issue?

      Thank you for any recommendations.
