Blower Controls

The Blower Motor delivers air to the interior of the vehicle. Its speed is controlled by the Blower Switch and the Blower Resistor Assembly. When the Ignition Switch is in RUN, battery voltage is applied to the Mode Selector. With the Mode Selector in any position except OFF, voltage is then supplied to the Blower Switch. With the Blower Switch in LO, voltage is applied across all the Blower Resistors and the Blower Motor; the Blower Motor runs at its slowest speed. With the Blower Switch in M1, one of the Blower Resistors is bypassed; the Blower Motor runs faster. When Blower Switch is in M2, two of the Blower Resistors are bypassed; the Blower Motor runs faster. When the Blower Switch is set to HI, the Blower Resistors are totally bypassed and battery voltage is applied directly to the Blower Motor; the Blower Motor runs at its fastest speed.
