    Unhappy A/C Blend door noise

    Hello, I am new to the forum and sure yall have had this question a dozen times but while going down the freeway with A/C on max, The blend doors make poping noise and air volume goes down like yuo swithched from max/recirculate air to normal outside air then a few min. later back to max. This goes on all the time and less noticable the slower you go but you still get the pop noise. any hints from anyone?

    Smile A/C blend door

    I thought these were elctronically controled, not by vacume like the older80's style ones were. I could be wrong though, I will look further into it this weekend and let yall know.
