Climate Control Question

[PHATBOYPIMP]

I am relatively new to the Hummer world as I purchased a 2006 H2 about six months ago. Since I purchased the vehicle I have had an intermittent problem with my passenger side climate control. No matter what the temperature is set at, it blasts the heat on the highest fan setting. If I shut off the car and wait a few minutes, it often corrects the problem. Due to the intermittent nature of the problem I have been resistant to take it to the dealer in hopes that it will become a more regular problem. I just expect them to say "Nothing happened when we tested it". Anyone have a similar problem or any advice on how to address this issue?
