Why is my Blend door not working properly?

The blend door is the problem if the air is cooler than in vent position.The problem is in the cooling system if you have to turn the temp knob at a cold position to feel the A/C. It is possible that the coolant circulation is being reduced by rust deposits in the heater core.
