blower motor resistor
I don't work for Webster. I have been repairing, installing, and troubleshooting electric and electronic circuits for about 30 years. The blower motor resistor is NOT a rHeostat. A rHeostat is a variable resistor. The blower motor resistor has fixed taps on it that give stepped blower control. The resistor itself is not the controlling device. The controlling device is the **** on the dash.
