1999 vauxhall corsa 1.4 - passenger window got a mind of its own! - tricklesthegreek

Hi,

My drivers window works fine on the button. But when I push it all the way down the passenger window automatically opens itself. I then push the passenger window button and it judders back up again. Yesterday as soon as let go (usually when you push it you can let go and it will automatically wind all the way up) it went back down again without me pressing the down button. In the end after about 8 attempts I got it back up. It only goes a bit haywire when the drivers window is fully down. But when you operate it on its own it is a bit temperamental.

Any ideas what it could be? My dad was wondering can I do a reset manually and if thats the case does anyone know how to do that for this model?

Thanks
