Without Air Conditioning

The Blower Motor delivers air to the interior of the vehicle. Its speed is controlled by the Blower Switch and the Blower Resistors. When the Ignition Switch is in RUN, battery voltage is supplied to the Blower Switch. With the Blower Switch in LO, voltage is supplied across all three Blower Resistors and the Blower Motor. The Blower Motor runs at its slowest speed. With the Blower Switch in MED 1, one of the three Blower Resistors is bypassed and the Blower Motor runs faster. With the Blower Switch in MED2, two of the three Blower Resistors are bypassed and the Blower Motor runs faster yet. When the Blower Switch is set to HI, battery voltage is supplied directly to the Blower Motor and the Blower Motor runs at its fastest speed.
