Heater Blows Cold Air/2003 MCSS
Never noticed it during the hot summer out here but now the heater blows only cold air no matter the setting on the controls.
The cooling system was flushed in 2008, mileage is 73,000.
Thanks

Welcome to the MCF forum. Sounds like a HVAC control problem. Fairly common problem. You will most likely need a new (or used)heater control unit. I happen to have 1 from an '01. Not sure if it's the same. My problem was the resistor block and the fan not working.
