The heater control valve on a 2001 Dodge Grand Caravan is located
inside the passenger compartment, behind the dashboard. It's not easily accessible and requires partial dashboard disassembly to reach. It's part of the HVAC (Heating, Ventilation, and Air Conditioning) system.
Because of its location and the complexity of accessing it, attempting this repair yourself is usually not recommended unless you have significant automotive experience. A professional mechanic will have the tools and knowledge to replace it correctly.
