rear windoe

hi got home from work rear window fully open ,partner dear of her driving to and fro work in it said she didn't touch switch ,does it open on its own ?took couple of goes to close it ,ignition on /off ,back on started car shut it off ignition back on and it closed any ideas please

if you keep you finger on the open button of the remote it will fully open .you can wind it back up with the key in the back door it is not a lock just there for shutting window but if you stop when it is half way up it will go back down again this also applies when using the back window switch, hope this helps
