Cosmin that's great news
Glad I could help.
If your sure the switches are OK then sounds like a dry solder joint or the relay is fried on the Vis
Part No: V23079A1003B301
Good luck with the rest of the car and most of all thanks for coming back to let us know.
Edit, just had a thought, if when you plugged the Vis motor in it is possible the gear over rotates and the cam actually hits both microswitches and then it locks up and will not move as both switches are open. Usually the resistance of the brown arm in the manifold stops this over run. have a quick look
