Take charge of your heater and A/C fan speeds with this Four Seasons switch, part number 20900, an HVAC Blower Motor Resistor / Switch that manages the current reaching the blower motor so each fan setting can run at its own speed. It is a direct-fit replacement for many vehicles, among them the 2002-2007 Mack LE, 2008-2010 Mack CHU and 2008-2010 Mack CXU. See the Buyer's Guide tab for the full list.
Four Seasons catalogs this part as an HVAC blower motor resistor, and it is also listed under the switch category. Both names refer to the same part.
- Precision engineered: Built with precision engineering for vehicle-specific applications.
- OE-style connectors: Connectors styled after the originals for a straightforward hookup to the harness.
- Quality contacts: Designed to help maintain proper electrical conductivity.
- A/C know-how: Backed by more than 50 years of Four Seasons mobile A/C experience. The product is engineered and tested with years of trouble-free operation as the goal.
Signs this part may need replacing include a blower that runs only on the highest setting, no fan output on one or more lower speeds, or fan speeds that do not match the selected setting. If a failed resistor is the cause, this unit replaces it. A blower motor, control switch or wiring fault can produce similar symptoms, so diagnose the circuit before replacing parts.
