Vehicle heating and ventilation Opel Vectra B

The heating and ventilation system consists of a fan located under the panel, ventilation nozzles located in the center and on the sides of the panel, and air ducts.

The control unit is located in the panel and controls dampers to divert and mix the air passing through the various parts of the heating and ventilation system. Cold air enters the system through a grill at the rear of the engine compartment. If necessary, the amount of air flow can be increased by turning on the fan. To heat the air, cold air is passed through the heater core heated by hot coolant. Depending on the position of the switches, the fresh air intake may be blocked while the air is being circulated inside the vehicle.
