What does the heater valve do?
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced

Where is the heater control valve on a 1999 dodge durango?
There is no heater control valve on this generation of dodges like there used to be... the water flows constantly through the heater valve.. the only control is a trap door that allows cab air to be run through the heater core and is controlled by a vacuum solenoid in the heater box.. the temp control is also vacuum operated but be sure to check the vacuum supply line coming in from the engine.... it has a check valve in it that can be keeping the controls from getting enough vacuum to operate properly.. if you don't have a mighty vac just get one of those packs of barbed vacuum fittings from your local shucks and bypass the valve temporarily and see if you get heat... hope this helps
