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.

Insertion depth of the sensor tube is marked or listed.

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