Hi, I have a Skoda mk3 Fabia 95bhp. I've had it from new and it is now 3 years old. I've noticed recently that when the fan(when either on cold or hot), is on, more noticeably in low mode(when you turn the fan speed to number 2) is making a whistling noise. Has anyone else had this issue or have any idea what could be causing it ?

 

thanks 

A no cost check you could try would be to remove, check and if required clean or replace the cabin filter and as much as possible clean or clear out the area, I favour a bottle brush and vacuum cleaner (great fun in such a restricted area).

 

After that I can think of more checking and cleaning but most people wouldn't be arsed to do (and neither would I unless I had a garage to give me shelter at this time of year).  If the cabin filter and inlet have lots of debris then you might need to follow the inlet further back to clear it out and perhaps cleaning and clearing of other bits but we can cross those bridges if you come to them. 

 

Unless others have the answer or you want to try the more checking and cleaning that may not solve or fully solve the issue the simplest solution is if it doesn't make the noise on the other settings then don't use fan speed 2 and leave it and see if the whistle progresses to other fan speeds as getting at the motor (and it's fan) if required is a PITA. 

 

The following video is just to give you the idea of how easy it is to check or replace the cabin filter, it's obviously a different model but similar process (well on  2015 Fabia IIRC).  Good luck. -

Many thanks for the suggestion 

Let us know how you get on and if you want or need to go further, that's if no one else comes up with the reason or solution.
