i get a "funk" out of my vetilation system

[malibuguy]

i had no clue this would turn out to be a common issue...so i didn't seach.

i pulse my A/C (since i'm a hypermiler) i run the vents often (like in the morning) I only use the A/C basically in the afternoon ride home.

i always run my A/C on recirculate, but whens its cool enough outside i vent outside air

i went to the parts store the other day, there was a filter listed in the book (but they were out of stock)...do they really not come with filters? Hell my '06 xB had one. I know how to get where its suppost to be, i'll dig in tomorrow after work.
