This little fiberglass board uses a series of progressive resistors to regulate the motorís 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 shouldnít have to settle for getting just one speed. Wanting to control your blower speed is why you would fix your resistor. Trust Corvette Mods to not only to get your 1969, 1970, or 1971 Corvette running right, but also making it an enjoyable place to be.
