Prevention
When you remove the condenser in cars equipped 5цилиндровым the engine, first of all, unscrew the line of a coolant conducting from the evaporator to the condenser.
Elements of management of the conditioner
|
1. Hatch of supply of fresh air and
air retsirkulyatsiya
2. External temperature sensor
3. Vacuum amplifier
it is intended for supply of fresh air in the hatch and for an air retsirkulyatsiya
4. Dashboard air inlet
5. Bilateral valve
it is intended for supply of fresh air in the hatch and for an air retsirkulyatsiya
6. Delivery fan of fresh air
|
7. Panel of the central air inlet and control system
8. Switch of supply of fresh air and retsirkulyatsiya mode
9. Switch of the air conditioner
10. Control unit conditioner
11. Ropes
connection on the control unit
connections with folding zaslonka
12. Openings for heating of feet
13. Consecutive resistance of the delivery fan |
Prevention
The devices described here, are located in a compartment of the engine and supplement elements of central air of air.
For replacement of the faulty vacuum block it is necessary to remove a heater, first of all.
Scheme of an arrangement of components
|
1. External temperature sensor
removal and installation:
uncover the ventilating hatch and a ware box
2. Hatch of supply of fresh air
3. The temperature sensor (on a cover)
4. The vacuum block of an operating zaslonka (having blown in feet and glasses)
Vacuum hoses
5. Connecting nest
for vacuum hoses and epektrichesky contacts of a heater
6. An opening for обдува feet
7. Vacuum block
ensures functioning of the central air zaslonka (a zaslonka regulating intake of air in openings for обдува feet and glasses) | 8. Adjusting engine
regulates the provision of a zaslonka of control of temperature (by means of a feedback potentiometer)
feedback potentiometer
9. Vacuum block
ensures functioning of an air zaslonka retsirkulirouyemogo/fresh air
10. The engine of the fan forcing fresh air
11. Heater
together with the evaporator
12. Control unit
regulates operation of the delivery fan
13. Switch of low pressure
it is intended for ensuring functioning of system of cooling |
