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

Central air

Air central air constantly is under a high pressure. At all do not disconnect refrigerator lines and do not remove any components of system, previously without having executed a discharge of the last. The discharge of central air of air should be made by strengths of the skilled expert in the conditions of a car-care center workshop.

Service procedures To/in are described in appropriate section of Head of Control and routine maintenance of the car.

Heating system

 PERFORMANCE ORDER

1. If the heater does not provide due heating of air submitted 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 submitted to heat up to the heat exchanger of a heater of cooling liquid of the engine to normal temperature. Replace the thermostat (see. Section Check of serviceability of functioning and thermostat replacement);
  2. Violation of passableness of an okhladitelny path that blocks supply of cooling liquid in the heater heat exchanger takes place. Feel the hoses connected to branch pipes on a back partition of an impellent compartment – both of them should be hot, otherwise passableness of a path is broken (hoses, the heat exchanger, or an operating zaslonka of a heater) are blocked. Disconnect hoses and make obratnopotochny washing of the heat exchanger. Wash out also both hoses;
  3. If to restore passableness of the heat exchanger by washing it is not possible, it is necessary to make its replacement (see. Section Removal and installation of the block and heater heat exchanger).

2. If speed of rotation of the fan of a heater does not correspond to chosen position of the corresponding switch on the system control panel, check a condition of a safety lock, connecting electroconducting, the relay, the switch and resistive assembly.
3. If the air outlet via deflectors at all is absent, undertake 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. Section Check of serviceability of functioning of the driving electromotor of the fan of a heater and its replacement).

4. Carpet moistening on a floor under the heater heat exchanger, or a steam-out via deflectors of air lines tell about leakages of the heat exchanger. Remove the heat exchanger (see. The section Removal and installation of the block and the heater heat exchanger) also replace it new (the heater heat exchanger is not subject to regenerative repair).
5. Check passableness of the drainage hose going from assembly of the heater/evaporator and laid of the spravy party of a partition. Blocking of this hose can lead to a steam-out from deflectors of air lines at heater inclusion.

Elimination of smells of central air of air

 PERFORMANCE ORDER

1. The unpleasant smells often arising at inclusion To/in are caused by formation of colonies of a mold on plates of the heat exchanger of the evaporator.
2. In the aerosol packaging, intended for service of central airs of air, it is possible to get special disinfectants 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 in a mode of the closed air circulation and for ten minutes turn on the heater fan for the maximum speed. For the purpose of drying of system include heating on the maximum intensity. Disconnect electroconducting from the compressor for the purpose of prevention of its operation.
3. Giving of means is usually carried out through a long hose. Remove rezistorny assembly of the electromotor of a drive of the fan of a heater (see. The section Check of serviceability of functioning of the driving electromotor of the fan of a heater and its replacement), enter a nozzle of a submitting nozzle into the formed opening and displace it to the left, having directed on 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 should be specified on a container label.
4. The best preventive measure against emergence of colonies of a mold in the heat exchanger of the evaporator is regular check of passableness of a drainage tube, and also short-term inclusion of a mode of removal of condensate after each distant trip with working conditioner for the purpose of evaporator drying.
