HEATER CONSTRUCTIONThe air-selection damper (located at the upper
part of the blower motor) can be used to select
either induction of outside air from the front
deck, or circulation of inside air.
The air taken in by the blower motor is passed
through the duct or evaporator (air conditioner
equipped vehicles) for forced supply to the
heater unit. At the right side of the heater unit is

ature control knob setting, the amount of blend#waAA
air which has passed through the heater core
and of cool air which has not passed through the
heater core is varied, thus regulating the temper-
ature.The area to which the air will
flow can be
selected by the mode-selection damper.

When the temperature control knob or
the heater control is rotated fully
counterclockwise toward the cool air
position, the upper side of the heater
core will be blocked up by the blend
air damper A. whereas the lower side
of the heater core
will be blocked up by
the blend air damper 8. As a result.
