Volkswagen Touran Service Manual: Electrical Components Not on Refrigerant Circuit

A/C Programmer -J127-

This programmer switches the refrigerant flow direction through the second evaporator if the temperature on the cooling fins on the second evaporator lowers to the freezing point for water (icing protection).
  A/C Programmer -J127-

Coolant Fan Control Module -J293-

  Note
There are different construction styles.
   
This control module switches on and off the A/C clutch and therefore the A/C compressor. It switches the coolant fan and calculates the pressure in the refrigerant circuit on vehicles with a High Pressure Sensor -G65- or A/C Pressure/Temperature Sensor -G395-.

Coolant Fan Control Module -J293

  Note
Available in different construction styles, some installed on coolant fan -arrows-.
   
This control module switches on and off the A/C clutch and therefore the A/C compressor. It switches the coolant fan and calculates the pressure in the refrigerant circuit on vehicles with a High Pressure Sensor -G65- or A/C Pressure/Temperature Sensor -G395-.
  Coolant Fan Control Module -J293

A/C Evaporator Temperature Switch -E33

Function:
The A/C Evaporator Temperature Switch -E33- determines the temperature between the evaporator cooling fans. It prevents the possibility of ice building up between the evaporator cooling fans because the current entry to the condenser magnetic clutch is interrupted when the temperature on the cooling fins lowers to the freezing point for humidity.
The insertion depth of the feeler tube is marked or indicated in the repair manual. Refer to → Rep. Gr.87.
  Note
Installed on VW vehicles with the A/C compressor drive above the ribbed belt
  A/C Evaporator Temperature Switch -E33

Evaporator Vent Temperature Sensor -G263- or Evaporator Temperature Sensor -G308

Function:
The Evaporator Vent Temperature Sensor -G263- or Evaporator Temperature Sensor -G308- determines the temperature behind the evaporator. This value goes to the air conditioning control module and serves as a reference signal for regulating the A/C compressor. This prevents the evaporator from icing up.
