Air Conditioner Controls (OPTIoN)
The air conditioning system uses the same
controls
as the heating system, except that
the air control knob has two extra
settings, described below. For
an
explanation of all the controls, see
“Heater Controls” earlier in this part.
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting recirculates most of the air inside
your vehicle. If it is used for long periods
of time, the air may become
dry. This
setting directs air through the upper air
vents.
. . .lo6
A/C: Use for normal cooling on hot days
This setting cools outside air and directs
through the upper air vents.
The air conditioner comtxessor oDerates
in
“MAX,” “NC” and ii VJ , ,% and
9 when the outside temperature is
a6&e freezing. When the air conditioner
is on, you may sometimes notice slight
changes in your vehicle’s engine speed
and power. This is normal because the
system is designed
to cycle the
compressor on and
off to keep the desirec
cooling and help fuel economy.

if you keep
your windows closed. On very hot days,
open the windows just long enough for
the hot air to escape.

normal cooling. For faster cooling
move the knob to
‘“AX.”

warming grid to remove fog from the rear
window.
Press the switch to turn on the defogger.
An indicator light will come on to remind
you that the defogger is on.
The defogger
will turn
off automatically after about ten
minutes of use. If you turn it on again, the
defogger will operate for about five
minutes only. You can also turn the
defogger
off by pressing the switch again.
Do not attach anything like a temporary
vehicle license
or a decal across the
defogger grid on the rear window.

damage the warming grid, and the
repairs wouldn’t be covered by your
warranty.

5 Cooling: System Service* -
Drain, flush and refill the system
with new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as specified. See “Coolant”
in the
Index. This provides proper
freeze and boil protection, corrosion inhibitor level and
maintains proper engine operating temperature.
Inspect hoses and replace if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside of the
radiator and air conditioning
condenser. Wash the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
