My cabin air recirc shuts off??

Hey!

I’m running 10.1.1 on my 23’ xlt er, for some reason my cabin air recirculation shuts off (reverts back to drawing outside air) after 5 minutes.

Not sure why this is, but its a pain in the ass right now as I’m waiting to pick up my kid from school and folks have their wood fireplaces going (it’s smoky where I’m parked).

I feel like I haven’t noticed this happening before, has anyone else experienced this? Is this normal?
