Check of serviceability of functioning and service of systems of heating and air conditioning

Air conditioning system

The air conditioning system constantly is under high pressure. Do not disconnect refrigerator lines at all and do not remove any components of system, previously without having executed a discharge of the last. The discharge of the air conditioning system has to be made by forces of the skilled expert in the conditions of a workshop of car service.

Procedures of service To/in are described in appropriate section of the Head Nastroyki and routine maintenance of the car.

System of heating

 PERFORMANCE ORDER

1. If the heater does not provide due heating of the air given to salon, one of the following can be the reason of such refusal:
  1. The thermostat is jammed in open situation that does not allow the cooling liquid of the engine given to the heat exchanger of a heater to heat up to normal temperature. Replace the thermostat (see the Section Check of Serviceability of Functioning and Replacement of the Thermostat);
  2. Violation of passability of a cooling path takes place that blocks supply of cooling liquid in the heater heat exchanger. Feel the hoses connected to branch pipes on a back partition of a motive compartment – both of them have to be hot, otherwise passability of a path is broken (hoses, the heat exchanger, or the operating heater gate are blocked). Disconnect hoses and make obratnopotochny washing of the heat exchanger. Wash out also both hoses;
  3. If it is not possible to restore passability of the heat exchanger by washing, it is necessary to make its replacement (see the Section Removal and installation of the block and heat exchanger of a heater).

2. If the speed of rotation of the fan of a heater does not correspond to the chosen position of the corresponding switch on the system control panel, check a condition of a safety lock, a connecting electrical wiring, the relay, switch and resistive assembly.
3. If the air outlet via deflectors is absent at all, take the following actions:

  1. Include ignition and activate the heater fan. Press an ear to the deflector and try to define aurally whether the driving motor functions;
  2. If the sounds confirming serviceability of functioning of the motor are absent, and resistive assembly as it should be, it is necessary to replace the motor (see the Section Check of Serviceability of Functioning of a Driving Electric Motor of the Fan of a Heater and its replacement).

4. Moistening of a carpet on a floor under the heater heat exchanger, or a steam-out via deflectors of air ducts is told about leakages of the heat exchanger. Remove the heat exchanger (see the Section Removal and installation of the block and heat exchanger of a heater) and replace it new (the heater heat exchanger is not subject to recovery repair).
5. Check passability of the drainage hose going from assembly of the heater/evaporator and laid the spravy party of a partition. Blocking of this hose can lead to a steam-out from deflectors of air ducts at inclusion of a heater.

Elimination of smells of the air conditioning system

 PERFORMANCE ORDER

1. The unpleasant smells often arising at inclusion To/in are caused by formation of colonies of a mold on evaporator heat exchanger plates.
2. The special disinfectants in aerosol packaging intended for service of air conditioning systems can be bought practically in any shop of automobile accessories. It is necessary to remember that the price of means is usually directly proportional to its efficiency. Switch system to the mode of the closed air circulation and for ten minutes turn on the heater fan on the maximum speed. For the purpose of drying of system include heating on the maximum intensity. Disconnect an electrical wiring from the compressor for the purpose of prevention of its operation.
3. Giving of means is usually carried out through a long hose. Remove resistor assembly of an electric motor of the drive of the fan of a heater (see the Section Check of Serviceability of Functioning of a Driving Electric Motor of the Fan of a Heater and its replacement), enter a nozzle of the giving nozzle into the formed opening and displace it to the left, having directed to the evaporator heat exchanger. Giving of means is carried out according to instructions of his manufacturer. Try to process all surface of the heat exchanger most fully. Duration of each operation cycle and intervals between series have to be specified on the label of a container.
4. The best preventive measure against emergence of colonies of a mold in the heat exchanger of the evaporator is regular check of passability of a drainage tube, and also short-term inclusion of the mode of removal of condensate after each distant trip with the working conditioner for the purpose of drying of the evaporator.
