2019 Trail Boss - windshield vent always on

[wahoowad]

The defrost vent on my 2019 Trail Boss is always on, even when I turn it off using the mode button. This occurs when the AC button is off too. Any DIY fix to resolve this? It gets way too hot around my head when running the heat.

find the mode door actuator, and see how it's moving, and perhaps try manually moving the levers for the doors to see what might be the problem (if any).  maybe that's just how it is, maybe a door is jammed open for some reason, maybe the actuator isn't moving properly.

Thanks! I’ll try this today

Note, that's the AI results for a google search, which are commonly wrong...  In particular, I would expect the a/c relay to be controlling the compressor, and removing it would not have any effect on the hvac system other than the compressor not coming on, when commanded to.
