Hi, I'm new to the site, so if this has been posted before, my apologies! Anyway, my rear wiper doesn't work although the washer does. I got a used motor from ebay, and plugged it in and it doesn't work either. However I notice that my original wiper motor has an external wire that the ebay one doesn't have. Is this likely to be the problem with the ebay one not working (i.e. my original is an upgraded one), or do I still have a problem with the car, for example, the relay? To get to the relay box looks like a nightmare, so any advice would be welcome. Oh, the fuse is OK by the way!
