Dorman - OE Solutions HVAC Blower Motor Resistor P/N:973-101
If a burnt-out resistor has left your blower fan stuck on one speed or not running at all, the Dorman blower motor resistor 973-003 is a direct replacement for the front HVAC system, designed to match the operation and performance of the original equipment. It fits many vehicles, among them the 1995-1999 Chevrolet C1500, the 1995-1999 Chevrolet K1500 and the 1995-2000 Chevrolet Tahoe. See the "Vehicles it fits" section for the full list.
The resistor sits in the blower motor circuit and controls the voltage sent to the fan motor. This helps provide the fan speeds you select at the climate controls for heating and cooling.
Signs this part may need replacing include a blower that works on only one setting or stops running entirely. A faulty blower motor, switch or wiring can cause similar symptoms, so diagnose the circuit before replacing the resistor.
