so at first I checked all fuses etc, then I started with the linkages and motor replaced the whole lot, linkage and motor, then I thought, well what if the motor on this one is knackered so tried it with my old one and nothing. then tried a whole new linkage and motor that I got cheap and same result, just doesn't do anything not even squirt water onto the windscreen so must be something electrical no?
Changed the massive relay and nothing, next I have to try a fuse on top of the battery and from there a new stalk... gutted
I cant understand it though as the old one had all the symptoms of just the linkage being knackered, it would work occasionally but really slow and then one day just gave up, I did used to force the wiper arm up a tiny bit and that would sometimes allow the wipers to move again but as they were which was intermittent, then one day nothing
