Evaporator Temperature Sensor / Switch: Description and Operation
A/C Evaporator Temperature Switch E33

A/C Evaporator Temperature Switch E33

Function:

A/C Evaporator Temperature Switch E33 determines the temperature between the evaporator cooling ribs. It prevents the possibility of ice build-up
between evaporator cooling ribs by interrupting the current supply to A/C clutch of A/C compressor when temperature at the cooling ribs sinks to the
freezing point for air moisture.

NOTE:  Installed in VW vehicles with A/C compressor driven via ribbed belt.
