This seems like too simple a question for this impressive review, but I can’t resist asking the question, since I am sure you will know what my problem is.

I get a very loud slapping sound from the center of the dash when I start my car with my climate control set in “auto” mode. It does not slap if I keep the control set to low fan. Is there something that would cause my vents to slap shut with such a loud noise?

I suspect it may be some kind of a vacuum thing, but it would be great to have a definitive answer and a possibly a little direction about a possible remedy.


Thank you for your help

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
