Help your blower fan run at the speed you choose with the Four Seasons 20504 front HVAC Blower Motor Resistor / Switch, a direct-fit replacement for the listed 1993-1995 Chevrolet Astro and 1993-1995 GMC Safari applications. The resistor works with the fan control to vary the current reaching the blower motor, which gives you the different fan speeds for heating, defrost and A/C airflow. This part is listed under both names: HVAC blower motor resistor and switch.

  • Vehicle-specific application: made for the listed 1993-1995 Chevrolet Astro and 1993-1995 GMC Safari models.
  • Precision engineered: designed for its intended front blower application.
  • Quality contacts: designed to provide proper electrical conductivity.
  • Engineered and tested: Four Seasons engineers and tests its products with the aim of years of trouble-free operation. The line is backed by more than 50 years of mobile A/C experience.

If a failed resistor is causing a blower that works on only some speeds or not at all, this Four Seasons switch replaces it. A fan control, wiring or blower motor fault can cause similar symptoms, so diagnose the circuit before replacing parts. See the Buyer's Guide tab for complete application details.

Frequently Asked Questions

What does the HVAC blower motor resistor / switch do?

It varies the electrical current reaching the blower motor so the fan can run at different speeds for heating, defrost and A/C airflow.

Is this 1993-1995 Chevrolet Astro switch the same part as a blower motor resistor?

Yes. Four Seasons 20504 is listed under both names, HVAC blower motor resistor and switch, and serves the front blower on the 1993-1995 Chevrolet Astro.

Will this switch fit my 1993-1995 GMC Safari?

It is listed for the 1993-1995 GMC Safari. The Buyer's Guide tab shows the full application details.

What are signs the blower motor resistor may need replacing?

Signs include a blower that runs on only some speeds, works only on high, or does not run at all. Other faults can cause the same symptoms, so diagnose the circuit first.

What features does the Four Seasons 20504 offer?

It is precision engineered for vehicle-specific applications and uses quality contacts designed for proper conductivity. It is backed by Four Seasons' more than 50 years of mobile A/C experience.
