My AC will only blow out of the defroster vents. It doesn't matter what you turn the **** too I don;t really care about it not changing but I want it to blow out the AC vents can anyone help identify which vacuum lines to change or point me to a thread that can thanks George

 

what year is your car and i can look it up for you

 

It's a 96 3.4 auto

 

i have had this same problem for years, though in the spring time it does it much less, and if i drive my care less frequently it doesnt do it as much, but yea, typically it only blows out my defrost vents and frosts up the windshield! well, atleast its fairly cold! haha, im still interested in the answer to this riddle though

 

the switch that controlls the switch is operated by vacuum, if check for under-hood leaks, then inspect the switch and what lines go to it
