How does recirculation mode with with climate control?
I was re-reading the owners manual today to refresh my memory on some of the functions and features.
The owners manuals states that recirculation mode "blocks" outside air from entering the vehicle. Preventing odors from getting into the cabin, helps cool the cabin down quicker, etc.
When recirculation mode is not on, where is the air that is being fed into the cabin being pulled from?
With recirculation mode on, what is closed off and pushing (more) air into the cabin?

Looking at the diagram in the manual, selecting the recirc mode switches the air inlet valve in the blower motor diverting air from the outside air inlet to the in-car air inlet. A vacuum is applied to the recirculation actuator which retracts closing the recirculation door. It doesn't show where the actual inlet is located but both seem to be part of the blower moter. I'll dig in further

The picture of the HVAC module which sits behind the dash beneath the defroster duct shows an integral air inlet with a drain and plumbing seals. I assume a duct links to the blower motor.
I'm sure the Forum experts who have changed the HVAC will be able to add to this.

I'm curious to see where the in-car air inlet is.
