Meal, driving a Ford Ka RU8 for many years. With the exception of a few small things, nothing had ever been broken, but the rear wiper has not been running for a few days now. Front wiper and spray nozzles at the rear + front still work perfectly. I then looked more closely and found out that the windscreen wiper worked again as soon as I opened the tailgate. At half-opened height the wiper then failed again…. e then found out for something that there were problems with the mass connection of the rear windscreen wiper engine, which was pulled over the rear flap hinge of the tailgate. Therefore I sprayed these with contact spray on the RU8 and exerted some pressure on the bolts…. first did not change but now the windscreen wiper does not work at all with closed or open flap. If someone had similar problems or knows someone like m the windshield wiper gets to run again? Thank you very much,
