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

  – the thermostat is not closed, therefore liquid is warmed up insufficiently and badly warms up a heater radiator – replace the thermostat (see subsection 4.3);
  – the heater hose that interferes with a liquid stream through a radiator is littered – disconnect hoses and wash out a radiator a water stream 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 the situation ON and turn on the fan (noise of the working electric motor should be listened).
  – if the rumble of the electric motor 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 openings pairs of cooling liquid get, in a radiator of a heater there is a leak. Replace a radiator.
4. Check purity of a drain hose of a moisture separator.
