This isn't working on my VRS, haven't looked into it yet, any common issues to check? Haven't had chance to look near it could be fuse lol

Eventually got 2 minutes to look at this, the connector that should be attached to the window I assume .... well isn't attached! Is this a common issue or what best way to reattach? There doesn't seem to be much room to work with, need have a good nosey in daylight, steamy rear window starting to do my head in!!!
