Does changing the setting move the air to other positions? Can you hear a hissing noise?

also if it does change from, say floor to top and such, the foam that seals the deflector doors may be gone.

Look under the plastic cover on the right side of the engine for a check valve with 3 hoses to it. Check to see if it is cracked or broken and leaking vacuum. If it is bad it is easy to replace and costs $5 - $8 to buy.
