This section tells you how to make your air system
work for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems,
you can control the heating,
cooling and ventilation in your van. Your vehicle also
has a flow-through ventilation system described later
in this section. The
knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the mode knob on the
far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger area
of your vehicle. This knob will allow you to adjust
the
Heater Controls
relative air temperature independently of the function knob
setting. Move
the knob toward the red area for warmer air.
Move the knob toward the blue area for cooler
air.
Mode Knob
If your vehicle does not have air conditioning, your
heater controls will look like this. The
right knob changes the heater setting.

conditioning controls will look like
this.
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle
of hot air.

MAX A/C: Move the right knob to MAX A/C for
maximum cooling. This setting puts the system in the
recirculation mode and helps
to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches
a comfortable temperature,
move the knob
to the right to place the air conditioning
system in the
A/C mode.

Rear Heater (Without Air Conditioning)
If you have a rear heater (without rear air conditioning),
the control switch is located on
the instrument panel. To
increase and decrease the flow
of heated air to the
rear floor vents, move the switch marked REAR HEAT
to the blower speed
you want.
The
knob has three speed positions. To increase the flow
of heated air, move the switch toward HIGH. To turn the
fan
off, move the switch to OFF.

Downloaded from www.Manualslib.com manuals search engine Rear Air Conditioning and Rear Heater
If your vehicle has a rear air conditioning and rear heater
system combination, controls are provided to regulate the
temperature, location and speed
of the airflow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side
of the control panel.
For warmer air, turn the knob toward the red area, and
for cooler air, turn the knob toward the blue area.
To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob to the left for floor vent airflow
or to the right for headliner
vent air flow.
Generally, the upper vents are used for air conditioning
and the
floor vents for heating. The control knob can be
set to any blend setting.
To adjust the
airflow speed, turn the fan control knob on
the left side of the control panel to the desired blower setting.
To activate the rear control, move the fan knob on the
front control to REAR CNTL.
Rear Passenger Control
The rear control works just like the front control. It will
allow second seat passengers
to adjust the controls as
they desire.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning 1 ~ ~ ting
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle
of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use
MAX A/C with the temperature knob in the
blue area when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as
the
vehicle has cooled down, so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting
it on LO
may enhance front A/C performance by allowing
trapped refrigerant in rear lines
to circulate.
When the air conditioning, DEFROST or
BLEND is on,
you may notice
a slight increase or decrease in engine
speed, due to compressor operation. This is normal
because the system is designed
to cycle the compressor
on and off
to keep the desired temperature. On
cold days,
use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best
if you keep your
windows closed while using it.
If you
use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater”
in the Index.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
blower fan to HI for a few moments before driving
off. This helps clear the intake ducts
of snow and
moisture, and reduces the chance of fogging the
inside
of your windows.
0 Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
Your vehicle has air vents in the center and
on the sides
of your instrument panel.
3-6

Downloaded from www.Manualslib.com manuals search engine You can move the vents from side to side or up and
down to direct the flow
of air, or close the vents
altogether. When
you close a vent, it will increase the
flow of air coming out
of any vents that are open.
Audio Systems
Your Delco Electronics audio system has been designed
to operate easily and give years of listening pleasure.
You will get the most enjoyment out of it if
you acquaint
yourself with it first. Find out what your Delco
Electronics system can do and how to operate all its
controls, to be sure you’re getting
the most out of the
advanced engineering that went
into it.
