no heat
Temperature is controlled by a manually operated air blend door in the heater air plenum chamber. When the temperature control **** is in the extreme COOL position (fully counterclockwise) all air bypasses the heater core.
When the temperature control **** is moved to the extreme WARM (fully clockwise) position, all air is directed through the heater core. When the temperature control **** is between COOL and WARM (between full counterclockwise and clockwise), air is directed through and around the heater core in rough proportion to the position of the temperature control **** between the extremes of its travel.
