7A–2 HEATING AND VENTILATION SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND SYSTEM OPERATION
HEATING AND VENTILATION
SYSTEMS
The base heater system is designed to provide heating,
ventilation, windshield defrosting, and side window de-
fogging.
The heater and fan assembly blower regulates the air-
flow from the air inlet for further processing and distribu-
tion.
The heater core transfers the heat from the engine cool-
ant to the inlet air.
The temperature door regulates the amount of the air
that passes through the heater core. The temperature
door also controls the temperature of the air by control-
ling the mix of the heated air and the ambient air.
The mode door regulates the flow and the distribution
of the processed air to the heater ducts and to the de-
froster ducts.
This console-mounted heating and ventilation panel
contains the following:
Three Rotary Control Knobs
1. The Rotary Temperature Control Knob

Actuates by cable.

Raises the temperature of the air entering the ve-
hicle by rotation toward the right, or the red portion
of the knob.
2. The Rotary Blower Control Knob

Turns on to operate the blower motor at four speeds.

Turns
to stop the blower.

Operates completely independently both from the
mode control that regulates the defroster door and
from the temperature control knob.
Changes the fan speed in any mode and at any
temperature setting.
3. The Rotary Mode Control Knob:

Actuates by cable.

Regulates the air distribution between the wind-
shield, the instrument panel, and the floor vents.
Push Knobs
1. The Rear Window Defogger Push Knob

Controls the rear window defogger.

Turns ON the rear window defogger when the push
knob is pressed and the indicator lamp is illumi-
nated.
2. The A/C Push Knob (if the vehicle is equipped with air
conditioning)

Controls the A/C.

Turns the A/C ON when the push knob is down.
However, if the blower control knob is OFF, the A/C
system is OFF, regardless of the position of the
A/C knob.
One Lever
1. The Fresh Air Control Lever

Operates by cable.

Switches between recirculating passenger compart-
ment air and bringing outside air into the passenger
compartment.

Draws in outside air when the lever is moved to the
left.

Recirculates inside air when the lever is moved to
the right.
