9.0 Heating system: 1 - heater radiator; 2 - heater fan; 3 - air distribution flap lever; 4 - air distribution flap drive; 5 - air distribution flap drive cable; 6 - damper cable for mixing hot and cold air
a - air intake; b - air outlet from windshield deflectors; c - air outlet from the deflectors on the instrument panel; d- air outlet from floor blower deflectors
Air intake for heating the cabin occurs through the air intake grille located under the windshield. Then the air is forced into the cabin by the fan. However, before entering the cabin, the air passes through the cabin air filter, and then is distributed to the deflectors by various flaps.
When the interior heating is turned on, the hot coolant supply valve to the heater opens. The air supplied through the air intake grille heats up when passing through the radiator plates of the heater and in this state is supplied to the interior of the car (see illustration 9.0). The heater radiator is located in the air distribution casing and is heated by hot coolant.
The heating system is based on regulating the temperature of the air supplied to the passenger compartment by increasing or decreasing the proportion of hot and cold air using air dampers.
A multi-speed fan is used to enhance the heating of the passenger compartment. Additional resistors are installed to ensure the operation of the heater fan at different rotation speeds. The resistors are located on the fan motor connection board. If the resistor fails, the board in the kit must be replaced.
Attention! RENAULT MEGANE cars can also be equipped with air conditioning.
