Sun Visors - Pontiac 1953 Owners Service Manual

ducts are controlled by two knobs
located centrally below the instrument
panel to the right of the steering column
and identified with a large "V" in the
center of the knob. The amount that
either the right or left knob is pulled out
will regulate the amount of air entering
for that particular duct.
The ventilating panes in the front
door windows can be pivoted to secure any degree of ventilation
with a minimum of drafts.
In cold weather, rain or snow, they
can be opened slightly to provide just
enough air circulation to prevent win-
dows and windshield steaming or
fogging. (If you have an underseat
heater, refer to page 17 for more
detailed information on ventilation.)
In extremely hot weather the front
ventilator can be turned almost com-
pletely around to a poSition that will scoop air into the car.
You will note that the ventilators lock when the little lever is turned
down. Thumb pressure on the button will release the lever for
opening the ventilator.
S UN VISORS-Folded
up against the
top directly in front of the driver and
passenger are two sun visors. The
visors may be moved toward the center
of the car, as well as swung around to
either the right or left to protect your
eyes when the sun is at either side.
FUSES -
The headlight wiring system on your Pontiac is protected
from damage in case of short circuits by a thermostatic circuit
breaker mounted on the light control switch. The circuit breaker
opens and closes intermittently, thereby reducing the current load
sufficiently to protect the wiring from damage. This action will con-
tinue until the cause is eliminated and is usually noticed due to a
snapping sound at approximately 3 to 5 second intervals. If you
are driving at night, the action of the Thermo Circuit Breaker will
be noticed by the headlamps burning intermittently. When this
