    Not that it is a problem but I have noticed the air door will change
    positions when the engine is under load when I am on a steep hil or
    accelerating for a loonger period of time than norma. It will change
    from vent and feet position to defrost. Once the load is back to
    normal it will change back to normal.

    Is this normal for this vehicle or should I be concerned for some
    problems in he future.

    cheers

    No it is not normal. The most common reason why it is doing that is because
    the small black check valve at the brake booster is bad. It is the one that
    is inline with the hose going into the dash.
    The cost is about $20. The other problem could be a vacuum leak within the
    HVAC vacuum system including a ruptured actuator diaphragm
