Was going for a drive in my brothers Fabia earlier and the strangest thing happened!

I opened the window for a while but when I started to close it, it went up a little way, went back down again, then it closed.

Any idea what could cause this?

have the same issue!

dont know what to do...

Feck knows, but my switches alternate which window they open, somedays the right switch opens the right window, somedays its the left window, somedays both switched work the same window

Answers on a post card please

Any ideas??
