Tangofox007, the vacuum elements which you refer to are the contraptions with a reddish top and black body with a metal element sticking out one end correct. If I recall correctly, these units are behind the dash and are somewhat difficult to get to. Is there anyway to isolate these units, or temporarily override them, let's say, make it so that the air travel pattern does not change from center vents to floor and window, or so that it flow to all the entire time and fix the problem??
