Hi folks. My car is a 2000, X reg 200K estate. The rear wiper started to stagger over the screen some time ago and then packed up completely. My local guy got it going again but it was still pausing for breath on its sweep. Its now stationery again. I renoved it at there is evidence of muck etc at the base of the shaft. The relay is clicking away so there is power. Does anyone know if it can be salvaged through dismantling and cleaning and if so how? Also, if its goosed can you buy a pattern part to replace? Regards.
