If the coolant temperature increases, the thermo-
stat capillary tube e_pands and acts on the valve
in the control system so that there is a smaller flow
of coolant. With less coolant flowing through, the
air temperature through the unit wiIl be lower and
this in turn affects the capillary tube which con-
tracts and permits more fluid to fIow through.
This cycle is repeated continuously so that a stable
air temperature is achieved.
Also included in the heating system of the car iS
the electricaIIy heated rear window. The amount
of heat is controlled by a switch on the dashboard
with which one of two output ranges can be
chosen. 1 5O watts and 4O watts. The control switch
is wired across a control relay (see wiring diagram)
