Four Seasons HVAC Blower Motor Resistor P/N:20351
Four Seasons 20664 blower motor resistor for the 1998-2001 Chevrolet Blazer and other vehicles sets the blower fan speed in the HVAC system.
A failing HVAC blower motor resistor can show up as a blower that runs on only some speeds or not at all. These signs alone do not prove the resistor is at fault, since a worn blower motor is another common cause.
This resistor is vehicle specific and has OE style connectors. Besides the Blazer, it fits the 1998-2001 GMC Jimmy and the 1998-2001 Oldsmobile Bravada.
