turn recirc on. that stops the vent flow.

When you're at speed on the highway, a low pressure area is created at the cowl area on the vehicle (this is how older cowl induction systems worked on musclecars). This low pressure area causes air to be forced into the vents and into the vehicle if the HVAC system is in the fresh air mode rather then recirc. So like Rollin Thunder stated, put the system in recirc mode and it should stop the air from coming in.

Yep... that's how old school cowl induction works. Not as effective as ram-air, but it works. I've actually been out of town for a few days and very busy lately since I've been back.
