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). |
|
|
|
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-. |
|
|
|
A/C Evaporator Temperature Switch -E33
| 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 |

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