SIERRA HEATER FAN PROBLEM

2002 Chevrolet Truck • V8 4WD Automatic • 360,000 miles

2002 Sierra heater fan has stopped blowing - is this a heater fan resister problem, and is there more than one part to be replaced?

Try directing power straight to the blower motor from the battery if it comes on-check blower relay, resistor/fan control module and blower switch
