Blower Motor Switch

Blower speeds are controlled by 4-position blower motor switch and resistor assembly located in evaporator case. Three of the 4 operating speeds (low, medium-low and medium-high) are controlled by a heater blower motor resistor and thermal limiter. Blower motor resistor is connected in series with 3 of the operating positions and ground. High speed is obtained by by-passing blower motor resistor. Blower motor does not operate when mode selector knob is in OFF position.
