I swapped in a junkyard sourced dash sensor. The problem did not go away. I still get cool air when the heat should be on. I decided to do additional tests since the sensor swapped in is not a known good part. As a test the outside air intake was completely blocked off with a piece of cardboard under the cabin air filter. I mistakenly referred to that as the Central Control Flap in my earlier post. The idea being that Fresh Air Intake Flap being blocked would answer my question about the flap allowing in to much air to heated. The was no change in the amount lack of heat. The system does pump out an awesome amount of cold air. When pressing the snowflake button the air gets colder. There is also coolant flowing through the heater core. When the blend door was done, so was the water pump and front motor mount. The system was refilled using an Airlift. I am thinking about pulling the power wire on the air conditioning compressor clutch to keep the air from coming on. Redneck diagnostics - problem is this still won't tell me why the system may always be cooling. I am not sold on clutch disconnect helping - it does seem that when hitting the snowflake button the RPM changes as it engages.
