1. If the heating of air in a heater is absent, the following can be the reasons:

  – The thermostat is not closed, therefore the liquid is warmed up insufficiently and badly warms up a heater radiator – replace the thermostat (subsection 4.3 see);
  – The heater hose that interferes with a liquid stream through a radiator is littered – disconnect hoses and wash out a radiator a stream of water from a hose;
  – If water does not pass through a heater radiator the radiator is littered and is subject to replacement.
2. If from exhaust outlets of air lines air does not arrive, arrive as follows:

  – Turn the ignition key in position ON and include the fan (noise of the working electric motor should be listened).
  – If the electric motor rumble is not listened, or if check shows that the switch and the block of resistors are serviceable, malfunction of the electric motor can be the reason.
3. If the rug is humidified, or through ventilating apertures steams of a cooling liquid in a heater radiator there is a leak get. Replace a radiator.
4. Check up cleanliness of a drain hose влагоотделителя.
