My front passenger window really squeaks when I use it. Is there an easy fix without

taking off the door card?

I have the same problem, both my windows on a W reg 1.4 fabia,

really annoying! gets even worse in the heat!

any help here would be much appreciated!

i agree with you both, it does my head in. im looking at taking the door card off and greasing everything rubber with silicine spray i think

Silicone spray all around the rubbers with the windows down should cure it. WD40 lasts about a week, silicone spray lasts for ever.
