Help your heater and A/C blower run at the fan speed you select with the Four Seasons HVAC Blower Motor Resistor / Switch, part number 20323. It fits many vehicles, among them the 1987-1994 Ford Tempo, 1987-1990 Ford Escort and 1987-1994 Mercury Topaz, and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full vehicle list and engine details.
A blower motor resistor sits in the blower circuit and lowers the voltage reaching the blower motor, which produces the lower fan settings. This part is cataloged as a switch, and Four Seasons describes it as an HVAC blower motor resistor, so you may see it listed under either name.
- Vehicle-specific applications: built for the listed vehicles rather than as a one-size-fits-all part.
- OE-style connectors: connectors styled like the original equipment for plug-in connection.
- Quality contacts: designed to maintain proper electrical conductivity.
- Engineered and tested: backed by Four Seasons' more than 50 years of mobile A/C experience.
Signs a blower motor resistor may need replacing include a blower that works on only some speeds, such as only on high, or a blower that does not run at all. A fuse, the fan speed switch, the wiring or the blower motor can cause similar symptoms, so diagnose the circuit before replacing parts.
