Control how fast your heater and A/C fan blows with this Four Seasons switch, the HVAC Blower Motor Resistor / Switch, part number 20396, which varies the current reaching the blower motor to set its fan speeds. It fits many vehicles, among them the 2004-2011 Dodge Dakota and the 2011 Ram Dakota, along with Mitsubishi, Mack and Peterbilt models. It is a direct-fit replacement for the listed applications.
Four Seasons lists this part under both names: HVAC blower motor resistor and switch. The company draws on more than 50 years of mobile A/C experience, and it engineers and tests its products to provide years of trouble-free operation.
- OE-style connectors: the connectors follow the original equipment style.
- Quality contacts: built to maintain proper electrical conductivity.
- Precision engineered: made with precision for its intended use.
- Vehicle-specific applications: cataloged for specific vehicles. See the "Vehicles it fits" section for the full list and engine details.
A blower that runs only on its highest setting, or that skips some fan speeds, may mean this resistor needs replacing. If a failed resistor is the cause, this unit replaces it. Diagnose the blower circuit before you order, because a worn blower motor or a wiring fault can cause similar symptoms.

Frequently Asked Questions
What does an HVAC blower motor resistor / switch do?
It varies the electrical current reaching the blower motor, so the heater and A/C fan can run at different speed settings.
Is this the right Dakota switch for my 2004-2011 Dodge Dakota blower fan?
Four Seasons 20396 is a direct-fit replacement for the 2004-2011 Dodge Dakota and the 2011 Ram Dakota. Check the "Vehicles it fits" section to confirm your exact vehicle.
What are signs the blower motor resistor may need replacing?
Common signs are a blower that works only on its highest setting or skips some fan speeds. Diagnose the circuit first, because a blower motor or wiring fault can cause similar symptoms.
What features does the Four Seasons 20396 have?
It has OE-style connectors and quality contacts for proper conductivity. It is precision engineered for vehicle-specific applications.
Why is this part listed as both a resistor and a switch?
Four Seasons describes 20396 as an HVAC blower motor resistor, and the catalog also classifies it as a switch, so it is listed under both names.
