Thanks for your input, I think you guys may be right about the blend door motor not working anymore and stuck in the hot postion.
I spent saturday taking the dash completly out and found this small black servo motor box that set on top of the heater box. There were some position indicating marks on the box and shaft which were aligned to one side. What I belive to be the hot postion, so I just jabbed a screw drive into the top of the shaft just to turn it a little bit. Put the dash back on the the air is not blowing so hot anymore, but the same temp at any setting.
How do you take the heater box out so that this motor can be replaced?
BTW- How do you take off the whole windshield arm from the post. Mine seem to be stuck, is there a tool?
