I have a 2003 Grand Marquis that is blowing air but will not get hot. I've checked the thermostat, anti freeze, and fuses. From what I gather there is a blend door valve that is prone to going bad and is coincidentally expensive to replace. Where is it and can I force it manually without replacing it?

Check the heater control valve and the heater core-if okay then deal with the air blend door/vacuum and actuator
