Driver window closing, then bouncing open again?

since i got my EP3 back from servicing, i noticed one niggly thing.

on my drivers window, which has the auto up/down option - if opened, then closed - it closes to the top, pauses a moment, then comes down (opens) on its own to around the window visor level, and stops there. if i close it again, if goes up, pauses, then opens again to the same level. however - if i lock the door, the window goes up (as per my alarm) and stays closed - so i know the motor works properly. when i unlock, it remains fully closed, until i open and try to close it again.

ideas?

mate take it to the auto eletrical they can hellp ya out sounds like the alarm system might be interfering or it might be wired wrong has it always doen this when did it start

had the alarm done 2 or so weeks ago, worked fine, no probs.

got a clutch installed last week, and when i drove it out, i noticed it straight away. not sure what they could have done that meddled with it though..

Yeah I think wires properly got damaged by the sounds of things as I said take to auto eletrical they will tell
