Ever since I got this car, I noticed that the heat / AC air volume does not seem high enough out of the vents. I can hear the fan really moving when set to high, so I know the fan is good. When I switch to RECIRC, I feel and hear a substantial difference in air volume out of the vents. I decided to pull the passenger side under-dash apart to see what might be going on. I see that the flap inside the car under the passenger dash closes and opens when recirc is turned on and off. I also checked the function of the recirc flap vacuum actuator above the pollen filter. It works properly, I can see that the door moves when commanded. I'm confused. I have this feeling that there is a flap, door, or some other obstruction blocking air flow when pulling fresh air. It sounds like the internal passage ways are under a lot of air pressure when in fresh air mode, with little air volume coming out the vents. Anybody have any ideas on this? p.s. the pollen filter was changed last year, and still looks good.
