I noticed yesterday that my re-circulate was not working. When I hit the button, fresh outside air is supposed to stop coming in but yesterday I kept smelling exhaust fumes from vehicles ahead. I go to hit the re-circulate button & the smell & air is still coming in when I put my hand up to it.

I need to know is it the filter that needs to be replaced or something more difficullt or expensive to replace. Any help is appreciated.

Thanks

Just met with the master tech. He said the recirculate mode does not cut off the outside air 100% he said fresh( or toxic) is still mixed in because of a regulation. (BS). He did tell me that the damper for the recirculate mode has a very porus foam gasket and that is what lets in the outside air on recirculate. off the record he said if the rubber gasket was changed to a non porus foam it would solve the problem but said it is not possible for lexus to do it because of the regulation that calls for a mix of fresh (or sulfer) to enter the cab on recirculate mode. Does anyone have a modification for the damper so we can solve the exhaust in the cab problem? It looks like lexus would rather poison

I think it was just user error. It works fine now.
