Take back control of every fan setting with the Four Seasons HVAC Blower Motor Resistor 20721. This direct-fit replacement is a common repair when a chevy Equinox blower motor resistor fails and the fan gets stuck on one speed or works only on high. The resistor sits in the blower motor circuit and sets the resistance for each speed, so moving the dash control actually changes airflow — when its contacts burn out or open up, some speeds drop away.

  • Quality contacts: help ensure proper conductivity through the blower circuit.
  • OE-style connectors: designed to plug into the factory harness for a clean fit.
  • Precision engineered: built for the specific listed vehicle applications.
  • Four Seasons quality: backed by decades of mobile A/C experience.

It drops into the 2006 Chevrolet Equinox, 2006-2010 Hummer H3, 2009-2010 Hummer H3T, 2006-2009 Pontiac Solstice, 2006 Pontiac Torrent, and 2007-2010 Saturn Sky. If a failed resistor is the cause of your Hummer H3 blower motor resistor trouble, this replaces it — see the Buyer's Guide tab for engine details.

Frequently Asked Questions

What does an hvac blower motor resistor do?

It sets the resistance in the blower motor circuit for each fan setting, so moving the dash control changes airflow speed. When it fails, one or more speeds stop working.

What are signs my blower motor resistor may need replacing?

The blower may run only on high, work on just one or two settings, or cut out on certain speeds. Diagnose the cause first, since the switch and wiring can cause similar symptoms.

Where is the 2006 chevy Equinox blower motor resistor location?

It typically mounts in the HVAC housing near the blower motor, often accessed under the passenger side of the dash. Consult the vehicle service information for exact access on your model.

Will this fit my Hummer H3?

Yes, it is a direct-fit replacement for the 2006-2010 Hummer H3 and 2009-2010 Hummer H3T, along with the other listed GM models. Check the Buyer's Guide tab to confirm your vehicle.

Does this resistor include connectors?

It features OE-style connectors designed to plug into the factory harness for a proper fit. Reuse or replace any other hardware as directed by the vehicle service procedure.
