    I have 2002 GC and I am curently have a problem with my air vent
    control. Currently, all air (AC or heat) comes through the defrost
    vents on the dash. None of the other locations work.

    Has anyone had similar problems. I called a dealer and they said that
    they have seen this problem before and it will require a lot of labor
    (labor = $$$) because the piece they need to replace is behind the
    dash. I was hoping that the issue is not mechanical but simply
    replacing the control behind the knob (maybe the connections are

    I am thinking of replacing if possible the switch and then go down the
    road of replacing the valve or whatever that channels the airflow if
    that does not work

    Thanks in advance

    that falls off the nipple on the intake manifold. hose swells out from
    oil and won't fit tight
