a/c blows through defroster

Check the vaccuum hose from the top of the manifold by the throttle body running back under the dash. 8 of 10 times when everything comes out of the defrost duct this has gotten knocked off.

Also Check the hard plastic tube inside the conduit that runs from the back of the engine to the HVAC controller . It gets brittle and small leak will not provide enough vacuum to operate the valves.

It took me weeks to figure it out last summers.

I have read several situations like your's. Most had a vac. leak however mine and another had ruptured diaphram in the UP/Down door actuator.

See diagram in FSM.
