Dial in every heater and A/C fan speed with the Four Seasons HVAC Blower Motor Resistor 20734. This Volvo Vnl blower motor resistor drops in as a direct-fit replacement for the 2002-2010 Volvo VNL and VNM, 2006-2010 Volvo VT, 2002-2009 Volvo VHD, and 2004 Volvo VN — see the Buyer's Guide tab for engine-level fitment.

The blower motor resistor sits in the HVAC circuit and drops voltage to the blower motor so the fan can run at each lower speed setting. If a failed resistor is the cause, you may lose one or more of the lower fan speeds while the highest speed still works, or lose the blower entirely.

  • Vehicle-specific application: built for the listed Volvo trucks.
  • OE-style connectors: plug into the factory harness.
  • Quality contacts: help ensure proper conductivity.
  • Precision engineered and tested, backed by Four Seasons' 50-plus years of mobile A/C experience.

Frequently Asked Questions

What does the Four Seasons blower motor resistor do?

It regulates current to the HVAC blower motor so the fan can run at its lower speed settings; the highest fan speed typically bypasses the resistor and runs at full voltage.

What are signs my blower motor resistor may need replacing?

Common signs include losing one or more of the lower fan speeds while high still works, or the blower not running at all. Diagnose the cause before replacing.

Which vehicles does the 20734 fit?

It fits the 2002-2010 Volvo VNL and VNM, 2006-2010 Volvo VT, 2002-2009 Volvo VHD, and 2004 Volvo VN. Check the Buyer's Guide tab for engine-level details.

Is this also called an hvac blower motor resistor?

Yes — it's the same component, listed as a blower motor resistor or hvac blower motor resistor. This one is built with OE-style connectors for the listed Volvo applications.

Does it use factory-style connectors?

Yes, it has OE-style connectors and quality contacts to help ensure proper conductivity on the listed applications.
