Warm up the engine to working temperature.
Establish a regulator of temperature of air on the lowest temperature, and the handle of management of the heater fan for the highest speed. Open car doors.
After the central air has provided a demanded temperature mode, check up temperature of two pipelines on a partition of the motor compartment, connected to the evaporator.
More thin pipeline connecting the evaporator with the condenser, should be колодным, and thicker pipeline connecting the evaporator with the compressor, should be even colder – 2–5 °С. If the pipeline connecting the evaporator with the compressor, much more warmly, than the pipeline connecting the evaporator with the condenser, system requires refuelling. Insert the thermometer into the central ventilating lattices of the panel of devices at work of a central air of air in a mode of the maximum cooling — the temperature shown by the thermometer, should be on 15-20 °С below air temperature in car salon. If the difference of temperatures is much less, possibly, the system requires refuelling.
If from ventilating lattices warm air moves, check up work муфты the conditioner compressor. The assistant should include air central air, at that time when you look at the forward party of the compressor. Муфта at inclusion should publish heard click, and a nave муфты should start to rotate.
If муфта does not work, check up the fuses located in the panel of devices.
If safety locks are serviceable, according to electric schemes check up serviceability of chains муфты the compressor and the pressure gauge.
If chains муфты the compressor and the pressure gauge are serviceable, possibly, has failed муфта.
If муфта the
compressor, the relay and their electric chains
are serviceable, probably, the system requires refuelling by a coolant. All further checks and repair of a central air of air are necessary for carrying out at servicing deport
