Well, all of the fresh air comes in through the front grill. The Fresh Air lever (blue one) in my bus open and closes the flaps. When they're open, air comes in while the car moves. It's kinda nice... except when it's 7 degrees outside and you're praying for the heat to work.
Did some research and took apart my front grill. The flaps were there and operated really well. Originally the flaps had this foam insulation that stuck inside the flap and, when closed, stopped air from leaking in. The foam in mine was gone.
Went to Home Depot and bought this:
It's weather stripping for automotive and marine applications. Has a glue that stands up to cold and weather. Figured it was a good buy.
Took my vents out and laid three strips each lengthwise across the inside of the vent. Here's a picture with the weather stripping installed:
Tested it out and it closes great. Theoretically, when I drive now, I should have the gush of cold air through these vents. If that still happens I'll have to open it back up and add some more insulation.
Took maybe 15 minutes cause I was moving slow.
Just checked it out and works really well. Barely any air coming through the vents! Woot!

that looks really good - i have similar problems (well my gf does - always moaning its cold!) - how did you undo the vents completely - mine are attached to a the 'switch')?
cheers,

Stuart,
The rod that connects to the switch fits through a piece of metal on the vent and is held in place with a spring or pin.
With the front grill/screen off, open the vent fully. You should be able to look under the vent and see where the rod comes through and has a hook that fits into the vent. With a pair of pliers or small fingers, you can get it off.

Thanks for this post! I was just driving my bus on the highway tonight and shoving various pieces of fabric and paper into the vents so I didn't freeze :) Going to Home Depot tomorrow!
