My BA MkII windscreen wipers died while I driving home last night, just when it started to shower. I've checked the wiper fuse, all good and tried replacing and still no go. I checked the wiper bolts, all good. There's no sound or turning noise when wipers are on. I'm a bit baffled as they were working fine days beforehand. Is there anything else suggested to check/try beforehand? Car is still under warranty and is due for a service so is this my only option? Thanks.. Phevor!
