Hi all. About a month ago a picked up my first car, a 2016 Fabia. The dealership noted 'applied lubricant front window mechanism'

Since driving it the past month, the window was become very squeaky! I've applied silicone spray WD40 today but no fix.

Any other thoughts? The noise is unbearable

Is it the glass or maybe internal mechanism thats making that noise. On my sons mk1 the window slides on what looks more like felt rather than rubber. That sounds like glass on rubber or a bad pulley in door. From memory it has to be dry silcone spray. Think WD40 do a specialist dry lube. If you have used standard silcone spray it may have to be cleaned off first.

Clean the window thoroughly first.

I have used a little french chalk / talcum powder, which worked well on the rubber bits.

Thanks. AG Falco

The exact same thing happens to me, especially during the dry seasons, like spring and summer. Now it's winter here in Chile, and the air is much more humid, so they don't make the noise. But it's unbearable. I hope someone knows how to fix it. I have a 2018 Fabia.
