Designed to manage how fast your cabin fan blows, this Four Seasons switch, the HVAC Blower Motor Resistor / Control Module, part number 20272, regulates the power sent to the blower motor so it runs at the speed chosen on the climate controls. It is a direct-fit replacement for the 2002-2007 Buick Rendezvous. See the "Vehicles it fits" section for engine details.
The part goes by more than one name. Four Seasons describes it as an HVAC blower motor control module, and it is also sold as a blower motor resistor.
- Quality contacts: intended to maintain proper conductivity.
- OE-style connectors: styled after the original equipment connectors.
- Vehicle-specific application: built for the listed vehicles, not as a universal part.
- Precision engineered: engineered and tested by Four Seasons, which draws on more than 50 years of mobile A/C experience.
A blower that runs only on high, skips some speeds or does not run at all can be a sign that this part may need replacing. If a failed resistor or control module is the cause, the 20272 replaces it. Diagnose the problem first, because a blower motor, fan-speed control or wiring fault can produce the same signs.
