2002 Ford Expedition Q&A
2002 Ford Expedition Question: Heater Will not blow hot.
I have a 2002 Ford Expedition and our heater blows cool, we have replaced the thermostat, added anti freeze, bought a control climate and it still is not heating. I just recently gottne this vehicle and I've heard different things that it could be. I am trying to avoid paying alot to get this fixed when it could be a minor problem that I could fix myself. Any suggestions would help, thank you. - rmaris7467
There are many variations to the heater controls depending on options, engines ect.....The heater has vacuum operated actuators that move heater flaps any of which could fail or loose a vacuum hose attached to it which would effect proper heater operation. The heater control valve is in the engine compartment near the firewall toward the center rear of the engine ensure the vacuum hose is attached to it. If you fell competent to doing some of the tests yourself, Autozone have some popular vehicle workshop manuals free on line on there website or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://www.alldatadiy.com/ - patrick mannion
