I have read thru several pages of threads and have not seen the problem I am having. My a/c and heater work, but it blows out about 50% in the floor, 30% out the dash vents, and about 20% defrost no matter where i try to make it blow on the display. It is stuck blowing out of all the vents. I would really like to be able to direct it again. What is broken. TIA

 

vacuum leak or the eatc control needs to rebuilt with new o-rings or replaced....
