Trying to sort out washer/wiper problem on my daughters Deisel Lupo - both front and rear washers wipers have stopped working after recent snow and cold weather. Fuses are all intact, can't hear any motor/relay noises when using the wiper/washer stalk switch. Tried bridging the fuses with ammeter to see if anything was happening when stalk was moved but nothing. I'm guessing that the stalk is probably broken although I suppose it may be the relay(?). Where are the relays?! Any help appreciated before garage rips me off.
