Vacumm whistle behind vent distribution knob... Posted by B Millar [Email] (#1109) [Profile/Gallery] (more from B Millar) on Fri, 7 Jun 2013 11:23:08 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'm not even going to begin to pretend I know anything about how this system works, but when I switch the air distribution to "0" aka off, there's a continuous air whooshing/whistling sound behind the knob. If I switch it to any of the ON positions it goes away. I don't use much heat or A/C (yeah, it works!) in this car (convertible), but I'm wondering if because it's part of the vacuum system if it would be contributing to a vacuum leak that may affect engine performance/idle/etc... Thanks!
