I believe the air comes in directly from the engine bay. In the summer months without the AC on you will get very hot if you turn the fan on as air is pulled into the cabin from the engine bay but if your turn on the recirculation button less heat will come in to the cabin. I did this and its true. The air is coming from around the plastic cover that covers the air cabin filter. The cover does not fit snuggly and is not a sealed cover. This is located on the bulkhead/firewall on the passenger side near the coolant tank.

I’ll send you a pic in a day or so in the meantime all you have to do is walk out to your C7 and look at the vent under the right side windshield /wipers. That is the inlet cabin air vent.

It's way too cold for playing with toys now. But seriously, if you try turning on just your ventilation fan on during a hot summer day the heat inside the cabin will increase. It's almost as if the heat was turned on even though it was not. Now turn on the recirc button and the heat will diminish. The vent you mentioned is very close to the cabin filter cover. They're neighbors.

How the mice get in is a great question. My guess is they do not come in through the intake, but rather go backwards up a floor vent from within the car.
But given how mice can get through very small openings, they can take pretty much any route they would like.

There is a photo on the C7 forum somewhere of an owner displaying a nest resting on his air cabin filter. The owner was in the process of removing the filter for replacement. I imagine ingress would most likely come from the cover that shields the air cabin filter. The only other possibility the mouse came through the battery cover into the cabin then entered into the vent duct located either under the seat or through the vent outlet on the dash. Are there any other vent outlets located inside the cabin?

I also ran into the same issue as the OP. No sign of a directional arrow on the OEM replacement. The one I took out had the lettering upside down so just did the same.
