Help your heating and A/C system deliver the fan speed you select with the Four Seasons 20600 switch, an HVAC blower motor control module / resistor that regulates how much power reaches the blower motor at each fan setting. It is a direct-fit replacement for many vehicles, among them the 2007-2009 Dodge Sprinter 2500, 2007-2009 Dodge Sprinter 3500 and 2007-2018 Freightliner Sprinter 2500, along with a wide range of Land Rover, Mercedes-Benz, Porsche and Volvo models. See the Buyer's Guide tab for the full list and engine details.
Four Seasons describes this part as an HVAC Blower Motor Control Module, and it is also sold as a blower motor resistor, so it is listed under both names. It is cataloged for front and rear positions. Four Seasons engineers and tests its products with years of trouble-free operation as the goal, drawing on more than 50 years of mobile A/C experience.
- OE-style connectors: connectors styled after the original equipment design.
- Quality contacts: designed to maintain proper electrical conductivity.
- Precision engineered: built with careful attention to detail.
- Vehicle-specific applications: made for the vehicles it is cataloged to fit.
Signs it may need replacing: the blower runs on only some speeds, will not run at all, or changes speed on its own. A blower motor, fuse, wiring or climate control head can cause similar symptoms, so diagnose the cause first. If the control module / resistor is at fault, this unit replaces it.
