Help your climate control run the cabin fan at its selected speeds with this Four Seasons switch, the HVAC Blower Motor Resistor / Switch, part number 20424. It is a front HVAC unit listed under both names. It fits many vehicles, among them the 2006-2014 Hyundai Sonata, 2007-2013 Hyundai Elantra and 2006-2020 Kia Optima. It is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
The blower motor resistor sets the current sent to the blower motor so the fan can run at the lower speed settings chosen on the HVAC control. If a failed resistor is the cause of missing fan speeds, this unit replaces it. Four Seasons products are engineered and tested with years of trouble-free operation in mind, backed by more than 50 years of mobile A/C experience.
- Quality contacts: designed for proper conductivity.
- Vehicle-specific: built for the listed applications.
- Connectors: OE-style.
- Position: front.
Signs this part may need replacing: the blower runs only on its highest setting, one or more fan speeds do not work, or the blower does not run at all. A blower motor, control switch or wiring fault can cause similar symptoms, so diagnose the cause before replacing the resistor.
