I'll be breaking a prefacelift ep3 soon with perfect working windows, if it's any help
I do I've taken 2 Renault Lagunas and my Rover 620 through, all with a faulty front window regulator. No bother at as it's not a pass/fail item as long as the window is up. Just open the door and talk to them/pass sheet to them. Not an issue. I had thought the drivers side had to work but it doesn't.So nobody knows for sure what the law is about this?
Seems it is a fail. Whether it does fail or not is another thing. Like checking trailer electrics or whether your rear fog illumination works. Will depend on who you get on the day. Best bet is to fix it.
