 PERFORMANCE ORDER

  1. Open a cowl.
  2. Having opened a cover, dump pressure in the cooling system, then merge cooling liquid (see the Head the Current leaving and service).
  3. Remove assembly of a receiver dehumidifier (see the Section Removal and installation of a receiver dehumidifier).
  4. Give a nut (1) of fastening of the broad valve.
  5. Remove pressure head lines assembled with a fixing plate (2), - at once to a zakuporta the open ends of lines in order to avoid hit to the working highway of system of moisture, prepare replaceable sealing rings.
  6. Remove from the mouths giving (4) and returnable (5) hoses of a heater, - prepare suitable caps.
  7. Shift against the stop back both front seats.
  8. Remove the dashboard (see the Head Kuzov).
  9. Remove the accelerator pedal.
  10. Remove a floor carpet in a driver's foot well.
  11. Remove the left sleeve of air supply in a back part of salon.
  12. Disunite the socket (6) of an electrical wiring of the sensor of temperature of the evaporator (B10/6).
  13. Remove the module of management of ignition (see the Head of the Power supply system and production of the fulfilled gases).
  14. Disunite sockets (7 and 8).
  15. Having hooked the suitable tool, remove drainage hoses (9).
  16. Remove basic arms of fastening of a casing of the evaporator to a rack And, panels of a floor and a partition.
  17. Remove a casing of the evaporator (10).
  18. Installation is made upside-down. New sealing rings before installation should be oiled compressor.
  19. In conclusion make cleaning of the processor memory of system of onboard self-diagnostics and execute synchronization of step electric motors of the drive of actuation mechanisms with use of the reader STAR DIAGNOSIS (ask for the help experts HUNDRED Mercedes-Benzs).

 PERFORMANCE ORDER

  1. Remove the broad valve (10) (see the Section Removal and installation of the broad valve).
  2. Disconnect an electrical wiring from the sensor of humidity of air (B31/2) and an electric motor of the drive of the gate of switching of the modes of air circulation (M2/5). Release and take aside plaits.
  3. Remove 5 spring clamps (4).
  4. Remove from an evaporator casing a casing of the fan of a heater (5).
  5. Turn out bolts (13 and 1) (TORX), remove 10 clamps (6) and lower the evaporator (7) assembled with a cover (8), having given it forward and down.
  6. Having slightly delayed an electric motor (M2/7) of the drive of the right mixing gate with the executive mechanism aside, remove clamps (6a).
  7. Uncover (8).
  8. Take the evaporator (7) from a casing.
  9. Wipe the pallet of a casing of the air distributor (12).
  10. Installation is made upside-down, - for greasing of sealing elements (14 and 15) of the broad valve and a casing of the evaporator use soap water (do not apply any oils and lubricants!). Apply a little lubricant on guides (16). Track correctness of landing of sealing elements and guides.
  11. In conclusion execute synchronization of driving electric motors with use of the reader STAR DIAGNOSIS and clear memory of system of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).
