Description

Turning on the HVAC blower and choosing its fan setting runs through one control: the Standard Ignition HVAC Blower Motor Switch, part number HS-321. It is a direct-fit replacement for the listed applications on the 1976-1987 Chevrolet Chevette, 1977-1982 Chevrolet Corvette and 1981-1987 Pontiac T1000, all engines.

The blower motor switch is the control the driver uses to switch the heating and ventilation blower on and select its fan setting. It routes power to the blower motor according to the position chosen. When the original switch wears, the blower may stop responding on some or all settings, or it may cut in and out. The blower motor, its resistor or the wiring can cause the same signs, so diagnose the circuit first. If the switch is the cause, HS-321 replaces it.

Part type: HVAC blower motor switch
Part number: HS-321 (also listed as HS321)
Quantity: the listed applications use one switch
Engine coverage: all engines on the listed years
