Official smelly heater thread.

^^^If you are smelling an exhaust smell in fresh mode, that is peculiar. I hope it is just a burn off period on the heater core. I say roll the windows down and crank it to fresh hot air! Air that baby out!

As for the "Pee Smelling" folks, try keeping it in fresh for a few days to a week at all times, and see if that smell disappears. After that, use recirc sparingly, always switching back to fresh when parked! That or stop pissing on your floormats! hehe

Have you ever noticed a small puddle of water on hot summer days coming from the front of a car when parked that had been using A/C? That is all the water that would be backing up if it is set to recirculate, making a nasty puddle in your ventilation system.
