Hi.
I have a 2004 Vectra C estate. The problem is, that the automatic tailgate is not opening properly. When I press the button on the boot, it clicks open ND moves about half an inch(sorry, not from UK, so imperial is not my type of units ). I then need to pull it an inch or two and then it slowly opens fully. If I pull it too much or too hard, it gets stuck and I need to close it again. No problem with closing. Read a lot of posts about closing faults that are fixed by cleaning the potenciometer, maybe that could be the case?
Thanks and greetings from Europe

Edit: Button on key(fob?) Unlocks it, but doesn't open it.
