I know what it is on mine, but it's not worth the hassle of messing with it. It happened when I replaced the Air Check Valve just to the right of the intake underneath the cowl. Basically, it controls whether you have air blowing in your car when you change the AC controls.
I think I don't have the hoses on completely sealed, but it hold vacuum just fine. Just an annoyance. Any issues with blowing cold air in the car?
