Question on A/C Recirc and non-recirc

[Hmmm2]

I just got my '08 H2 and have noticed that when the A/C in set on recirculation I am still getting outdoor smells and odors... same as when recirc is not on. Is this an inherent problem or is mine not recirculating properly? I passed a man cutting his lawn and I swear the lawnmower with grass was inside with me!

L, I could never figure out how exactly mine works. Sometimes it will Recirc (green light on), sometimes it just flashes then remains off (no green light). I think it's got to do with either the Auto or if you adjust the fan manually. But for the life of me could not figure out which is which.

Most irritating when you see a dead skunk up ahead on Hawthorne and you're scrambling to turn on the recirc before the smell hits you and 2 out of 5 times it WON'T turn on!!!

LOLOL .. What's with all the dead skunks on Hawthorne recently anyways?!?! Especially that section between Silver Spur and PV Drive... actually Silver Spur and Black Horse, to be more exact?? Must be spring. Phew.

Thanks for your response, Horace.

I have no sympathy for you people that are complaining about the smell of fresh cut grass inside your vehicle...... I could only wish/pray for that smell here in the Chicagoland area We have had tons of snow and cold.

With the recirculate on you really should not smell anything from the outside short of something so strong it penetrates anyway (like a fresh dead skunk that you straddled). My Z06 has no cats and when its not on recirculate I occasionally get an exhaust odor inside the car, when on recirc I get no odor at all. Both the H2 and that car will flash sometimes and shut off, I think it has to do with the initial setting.

Geez if I remember right I thought I read in the manual that the H2 always recirculates even when off.

Reading the owners manual I guess would make sense Although I just usually figure out the hard way how to work stuff
