I have a 87 ford mustang 2.3 . The air conditioner will stop blowing from normal vents and blow from defroster vent. After a few minutes, it blows from the ac vents again.


There is a vacume hose going from the intake manifold to the passenger compartment. This hose has a check valve and a vacume resivore. When you steap on the gas the manifold vacume drops and the a/c goes to the default mode (defrost). The hose is small like a ball point pen's ink tube. sometimes the hose rots and leaks.

Defrost blows cold air


Sounds like you have a plenum door that is not opening when you go into defrost mode. You will have to check all your vacuum hoses and switching valves under the dash to see which one is not working. Hope this helps.
