Hello everyone! icon_smile.gif
I have a VW Vento 1.9 1Z with a fan that always runs on setting III.
Thermostat switch already replaced.
Fuses on the battery also checked.
Whether the air conditioning is on or off, the fan keeps running and running and running.
Does anyone have a suggestion?

Fan control unit is faulty or the wiring to the thermostat switch is shorted.
