on all models. Two small permanent magnet motor
and impeller assemblies (Fig. 1-13) force air, at one of
two speeds through each upper air vent duct. A three:
( O f f , Low, High) position switch on the instrument
panel controls operation of the motors (Fig. 1-14).
The two motor speeds are achieved by use of a 3.35
ohm resistance wire to each motor. Approximately 106
inches of resistance wire provides low speed while high
speed uses no resistance. The motor harness is routed
on the upper inner side of the dash to each motor.
