Regain control of your rear cabin fan speeds with the Four Seasons HVAC Blower Motor Resistor 20488, a direct-fit replacement for the 1992-2005 Chevrolet Astro and 1993-2005 GMC Safari. This resistor sits in the rear blower circuit and steps the voltage feeding the rear blower motor, setting the lower and intermediate fan speeds so you get the airflow you select at the control panel. See the Buyer's Guide tab for engine-specific applications.

  • Vehicle-specific application: engineered for the listed rear-HVAC applications for a proper fit.
  • Quality contacts: designed to ensure proper conductivity through the resistor circuit.
  • OE-style connectors: mate with the factory harness.
  • Backed by Four Seasons: over 50 years of mobile A/C experience behind every part.

Signs this part may need replacing include a rear blower that runs only on high, drops out on one or more speeds, or stops responding to the speed selector. If a failed resistor is the cause of those symptoms, this unit replaces it; diagnose the circuit before ordering.

Frequently Asked Questions

What does this blower motor resistor do?

It adds resistance in the rear blower circuit to set the lower and intermediate fan speeds, so the motor runs at the speed you select on the HVAC control.

Which vehicles does the 20488 fit?

It is a direct-fit replacement for the 1992-2005 Chevrolet Astro and 1993-2005 GMC Safari. Check the Buyer's Guide tab for engine-specific applications.

Why does my rear fan only work on high?

A failed resistor often lets the blower run only on high while lower speeds drop out. If the resistor is the cause, this part replaces it; confirm the circuit first.

Does it use the factory connector?

Yes. It features OE-style connectors made to mate with the factory harness for a straightforward installation.

Is this a front or rear unit?

This is a rear HVAC blower motor resistor for the listed applications.
