SOURCE: Toyota Corolla AC/heater fan only works intermittently

I had the same problem on my 2004 Corrolla and ultimately it only worked on high. The dealer charged me $45 diagnostic fee and almost immediately told me it was a part called the blower resister. They knew the answer right there and then but only realesed it when I agreed to pay the diagnostic. They charged me 179.00 to fix the AC and later I found out the part cost $8.95 and a novice could have replaced it themselves.

SOURCE: vent selector inop

U have either lost the vacuum to the mode selector switch (in the dash control) or the vacuum mode selector switch is leaking in the ac/heater control in the dash, u can usually hear a hiss if it is leaking. the vacuum source is the engine, a small hose runs through the firewall on the passenger side to the switch from the eng vacuum source.

SOURCE: ac blows through defroster on max

The Climate control system in your truck has a gate that changes postition in order to change the flow of air from your face to defrost. The door is actuated by vacuum. Yours is still working otherwise it would be on defrost all the time. So you do have partial vacuum to the actuator but not enough to keep it in position when on high. Sounds like you have a vacuum leak but not bad enough (yet) to totally disable the gate.
