Manage rear-cabin blower fan speeds with the Four Seasons HVAC Blower Motor Resistor / Switch 20488, the Astro switch that installs as a direct-fit replacement for the 1992-2005 Chevrolet Astro and 1993-2005 GMC Safari. This rear HVAC blower motor resistor adds resistance in the rear blower motor circuit so the fan control can set each speed; on the highest setting the motor typically runs with the resistor bypassed.
Vehicle-specific application: built for the listed Astro and Safari applications.
Quality contacts: intended to ensure proper conductivity through the circuit.
OE-style connectors: designed to match the factory harness plug.
Tested build: engineered and tested by Four Seasons, backed by over 50 years of mobile A/C experience.
Signs the original resistor may need replacing include a rear blower that only works on one or two speeds, drops the lower settings, or stops responding entirely. Because those symptoms can have other causes, diagnose the circuit first; if a failed resistor is the cause, this replaces it. A common Safari switch and rear-HVAC repair for these vans.
