Can anyone help? I have a 2011 fabia and the passenger side front electric window keeps failing to work. On its first service the dealer said they could find no fault so does anyone have any much appreciated suggestions?

I have the same problem when it is freezing and damp sometimes the windows won't open other times the open of their own accord. I think they are faulty window switches.

Had it a few times on mines too.

The dealer said its the computer that controls everything somtimes looses sync with the sensors and switches so it wont operate them until it re-sets as it cant "see them". Usually works again if you turn the car off and leave it for a while then go back.

Just a bug i suppose.
