Did a search but couldn't find anything.
If I take the a/c off recirculate while going down the road, all is well but when stopped for more than a minute or so, it goes back to recirculate by itself and stays there until I switch to recirculate and back to outside air after rolling again.
It's a dual climate control but not on auto.
Is this normal? I was guessing a vacuum leak that leaves it too weak to hold outside vent air at idle.
Thanks for any help.
