To check for a vacuum leak on a 2003 Dodge Dakota heater, start by visually inspecting all vacuum hoses for cracks, breaks, or loose connections. Use a vacuum gauge to measure the vacuum levels; low readings can indicate a leak. Additionally, you can spray a carburetor cleaner or soapy water around the hoses and intake manifold while the engine is running; if the idle changes, it suggests a leak is present. Finally, consider using a smoke machine for a more precise detection of leaks in the system.

92 Dodge truck vacuum hose routing for my heater control?
For a 1992 Dodge truck, the vacuum hose routing for the heater control typically involves connecting a vacuum source from the intake manifold to the heater control valve. This hose should run to the control switch on the dashboard, which then distributes vacuum to the appropriate actuator for controlling the heat and air settings. Ensure that all connections are secure and check for any leaks in the hoses, as they can affect the performance of the heater controls. Refer to a service manual for specific diagrams and routing details for your exact model.

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
