General information and device
Air intake for heating the passenger compartment occurs through the air intake grille with a dust filter, located under the windshield. Outside air passes through the dust filter (air purifier) and enters the fan casing, and from there - into the heater radiator, from where, already heated, it enters the air distribution flaps to the deflectors in the cabin.
Depending on the position of the heater control, a greater or lesser volume of the outside air taken in passes through the heater radiator. The heater radiator is located inside the heater housing and is heated by the hot coolant passing through the heater. The air heated in the heater radiator is supplied to the passenger compartment. The temperature of the air supplied to the passenger compartment is regulated by mixing fresh outside air and air heated in the heater using the air distribution flap.
To increase the volume of air supplied for heating the passenger compartment, a fan is installed. The fan can operate at different intensities (speeds), which is ensured by the corresponding resistors installed on the fan connection board. In case of a malfunction, the board is replaced as a set (see illustration 9.0, 9.0a and 9.0b).
