I am assuming you are referring to the control for the heater that dictates where the air flow will come out? Floor, defrost, vents, etc? If so, there is a vaccuum controlled flap inside the heating system that controls that. I have the same problem with my 2002 Wrangler. Apparently, it is one hell of a job since it is buried and you literally have to take the whole dash of the car appart to get to it. A buddy of mine is a mechanic and he told me it would probably take him a few hours just to get to the part, let alone fix the issue, so I said to heck with it.

The heater door control on a Blazer can be replaced by purchasing a new one. The heater vent will pop out with a little nudge from a flat tipped screw driver. Then insert the new heater vent door control.
Like most cars. The heater control valve is located inside the closed compartment with the heater core and the and the AC condenser. It is a door flap that seperates the heated air from the outside air, or the AC air.
There isn't a water control valve. The airflow is directed around the heater core by a door to control temp.
