Having trouble getting hot air out of your 1970, 1971, 1972 El Camino's heater system on anything other than a 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 Nova understands that sometimes, just a little heat is all that you need. Trust Eckler's El Camino to not only to get your 1970, 1971,1972 El Camino running right, but also making it an enjoyable place to be.
