look at the above link and you should be able to figure out what is going on with your system.
it is most likely the door flap located on the passenger side under the dash is not closing all the way.
have your wife move the temp. adjuster from cold to hot while you are looking at that side.
give me a call if you need some help.

are yopu talking about the blend gate? (off diagram) if so that is moving freely with the control hear it moving back and forth and also the temp changes from cold to hot
