Does anybody know which port (and location) in the cabin is used for the re-circulating air? Meaning, which port the air from the cabin is sucked into.

I have tried looking through the repair manuals on the techinfo site, but the vent system is really not detailed very well.

For the inevitable question, why:

I am planning to install an ozone generator and air freshener system.

I would think you need to focus on the area with the cabin air filter, which is located behind the glovebox.

Thanks.

I was poking around in there earlier, and I am reasonably certain that the cabin air is sucked in through the small vents on either side of the center console. The cooler evaporator and heat radiator appears to be behind the radio and there is a box there connected to those side vents.

Those side vents are Air Duct No. 2 and no. 3 in this diagram, I believe.
