Control Assembly: Description and Operation

Control Lever Assembly




The vehicle has cable-control-type to control by cable the mode and temperature of the heater unit and the mode door for the air source of the blower assembly.

Ventilation

Set "AIR SOURCE SELECT LEVER" to "FRESH" position and turn on the blower fan. Heating can be done in this lever position, sending in fresh air from outside. The blower fan also serves to deliver fresh outside air to the vehicle interior to assure adequate ventilation.

Air Select Lever




The air select knob allows you to direct heated air into the passenger compartment through different outlets.
1. Vent - In this position, air is discharged from the upper air outlet. Air quantity is controlled by the fan control lever.
2. Bi-level - In this position, air flow is divided between the upper air outlets and the floor air outlets, with warmed air delivered to the floor outlets than the air delivered to the upper air outlets when the temperature lever is in middle position.
3. Foot - In this position, air flow is delivered to the foot, while sending approx. a small amount of air to the windshield.
4. Def/Foot - In this position, airflow is delivered to the foot, while sending approx. 40% of total amount of air to the windshield.
5. Defrost - In this position, most of the air is delivered to the windshield and a small amount is delivered to the side windows.
Selecting this mode allows air conditioning system to work while the fan switch is turned to the on position, even is the A/C switch is off.

Moving the air source select lever to the "CIRC" position provides quickest heat delivery by closing the blower assembly mode door. In this position, outside air is not delivered to the passenger compartment.

Air Source Select Lever
The intake of the outside air and the circulation of the inside air are controlled by sliding this lever left or right.

Fan Control Lever
This controls the blower motor speed to regulate the amount of air delivered to the defrost, foot, and ventilation ducts:
1. Low
2. Medium Low
3. Medium High
4. High

Temperature Control Lever
When the temperature control knob is in the "COLD" position, the air mix door closes to block the flow air to the heater core.

When the temperature control knob is in the "HOT" position, the air mix door opens to allow air to pass through the heater core and heat the passenger compartment.

Placing the knob in the intermediate position will cause a lesser or greater amount of air to reach the heater core. In this mode the passenger compartment temperature can be regulated.

Indication
- The AUTO LED is turned off.
- Currently selected modes for the Mode and Intake are respectively indicated.
- The A/C LED remains turned on even if the compressor has been turned off due to the given temperature level of the outside air. Pressing the air conditioning switch in this state turns off the A/C LED.

Mode Switch
1. Pressing the VENT, B/L or FOOT switch selects the corresponding mode.
2. When the Auto is selected for the Mode and Intake, pressing the mode switch fixes the intake to the immediately preceding status.
