Manage how fast your cabin fan blows with the Four Seasons HVAC Blower Motor Resistor / Switch 20478, a direct-fit replacement for the listed applications on the 2010-2019 Fiat 500, the 2010-2019 Fiat 500 / 500E and the 2016-2019 Fiat 500X. See the Buyer's Guide tab for engine details.

A blower motor resistor controls the current sent to the HVAC blower motor, so the fan can run at the different speeds selected on the climate controls. If a failed resistor is the cause of a blower that runs only on its highest setting, or of fan speeds that have stopped working, this unit replaces it. Diagnose the cause first, because a control switch, the wiring or the blower motor itself can produce similar symptoms. Four Seasons describes this part as an HVAC blower motor resistor, and it is also catalogued as a switch, so you may see this Four Seasons switch listed under either name.

  • Vehicle-specific applications: built for the listed Fiat applications.
  • Precision engineered: engineered and tested by Four Seasons, which draws on more than 50 years of mobile A/C experience.
  • OE-style connectors: for connecting to the vehicle's blower circuit.
