Heater valve is normally at the engine side of the firewall, Follow the two smaller diameter coolant hoses that go from the engine to the heater core. Look at a parts source like www.rockauto.com they may have an image of the part once you know what it looks like you may be able to find it easier. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info 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 can get a one week subscription or year subscription very cheap. The information is 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 try http://bit.ly/mitchell_repair_manuals_online
