Silent fan
Is there a way to make temperature sensor fan (near the lamp) work silently. Now it has irritating noise.
Re: Silent fan
I never heard it in my vehicle. Maybe it just needs a thorough cleaning?

Re: Silent fan
One of mine stopped working - it was jammed with fine debris.
Try blowing it out with a straw or similar

Re: Silent fan
I did exactly this and fan started to whirr. Was very silent before. I have 3 spare of the same type (fan+sensor) and all are noisy. Decided to clean the sensor on the working one because of visible dust and this was my mistake. Now all are noisy. Maybe WD40 may help. Any idea which pins are for fan on 4-pin connector? I guess it is 12V.
