    Stopped blowing air through the front vents. Started with a clicking noise under the dash and then it would finally allow air through vents. Then it stopped clicking and no air comes through the front vents.

    A/C comes out of driver side vents....heat comes out of the passenger side vents. No noises before. Does not happen everytime, but seems to happen when it is hot outside and you want a/c.

    Everything was working fine and one day I went to start my car and a loud clicking sound started in the center of my dash and the heat stopped coming out of the chest level vents and sometimes the defroster vents. now it's summer and the problem is intermittent with the AC (MOSTLY no AC chest level)I haven't had the money to have the dash torn down and replace the cervo or door gears. I hear it is a big job, and lots of hours of labor.

    the car runs and sounds fine. I did not fluttering under the dash like the vents were moving on there own. Now that its cold out and I turn heat up it comes out cold. When I play with the temp knob eventually the heat starts working but still not 100%

    a/c doors make clicking sound at startup, at first it would correct itself aftert 5 minutes or so, now it only works when it wants and never through front vents.
