Heater problem
2005 Dodge Ram V8 Four Wheel Drive Automatic

the control selector knob will turn from defrost to mid point heat to floor heat, but the air flow is very minimal and will not change positioning. The blower fan is working fine just, no changes to the zoning.

Do you
have the same problem?

Hi
The vent doors are run by vacuum. Start by removing the control panel and listening for leaks. Also, follow the vacuum lines and check for damaged or broken lines. Especially check near the firewall where the lines go through to the engine and near the engine where they could melt.

Let me know what you find.

Joe
