What is your question?
My heater blows cold. When first turning it on it blows hot for a quick second then stays cold. What could be causing this?

A defective blend door system or actuator. I would have your Heating System scanned. Also be sure to check the heater control valve, it may be worn out as well, the valve is the easiest to check, it is inline with the heater hoses.
