You may look into seeing if the blend door is stuck open. That may cause your problem.

there's a vacuum actuated dohickie in the ventilation system that occasionally sticks. If you pull the controls out you can see the vacuum lines. What I have done in the past is pulled the lines out and both pressurized them and also applied additional vacuum with a littel hand pump to unfreeze the dohickie.

Sorry about using such technical jargon.
