A/C Evaporator Temperature Switch -E33-
WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
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 Service Information. Refer to the appropriate service information .
