Designed to manage front blower motor speed so cabin airflow follows your fan setting, the Four Seasons HVAC Blower Motor Control Module / Switch, part number 20273, is a direct-fit Pilot switch replacement for the 2003-2008 Honda Pilot and the 2001-2006 Acura MDX. It is cataloged as a switch, while Four Seasons calls it an HVAC Blower Motor Control Module. Both names refer to this same part.
The module works in the front HVAC system's blower circuit and controls how fast the blower motor runs at each fan-speed selection. When it fails, the fan may stop responding to the climate controls.
- Vehicle-specific application: built for the listed applications.
- Quality contacts: provide proper electrical conductivity.
- OE-style connectors: follow the original-equipment connector style.
- Engineered and tested: Four Seasons engineers and tests this module and backs it with more than 50 years of mobile A/C experience.
Signs this part may need replacing: the front blower runs on only some speeds, stays stuck on one speed, or does not run at all. A blower motor, control switch or wiring fault can cause the same symptoms, so diagnose the circuit before you replace parts. See the Buyer's Guide tab for complete fitment details.
