    Hissing from dash?

    Hey guys, my car started doing something funny. When I start the car, there is an audible hissing sund coming from the passenger side under the dash. I haven't taken anything apart to see what's up, but it is very strange. Sounds like an air leak.

    Any ideas?

    The heat and aircon still work fine.

    Haven't checked the cruise, will check that tonight.
    It isn't the fan, that makes it's own noise, but this is definitely an air leak sort of noise. I think it may have to do with the vents.

    i tried checking the air flow:
    Defrost/defog worked
    So did the vent (upper)
    Don't believe the passenger footwell was working.

    an airleak won't necessarily mean that you'll lose your hvac controls... the controls in my chrysler worked great. The hissing noise did go away at some settings though. Is your hissing changing when you change your vents?
