  • High Quality Replacement Resistor
  • For Models With Factory AC Built After April 17, 1968
Having trouble getting hot air out of your heater system on anything other than at high speed? The problem is most likely your blower motor resistor! This little fiberglass board uses a series of progressive resistors to regulate the motor’s speed throughout the switch range. The highest speed of the heater blower motor is not controlled by the resistor. Because of this, when the resistor fails, the fan will often work on the highest speed setting and not any lower speed. You shouldn’t have to settle for getting just one speed. Ecklers Trucks understands that, sometimes, just a little heat is all that you need. Trust Eckler's  to not only to get your Truck running right, but also making it an enjoyable place to be.
