Had a problem with windscreen wash system, changed the fuse and the pump started to work but no rear wash. Went to change the pump but found a broken hose so I did a DIY repair but still no rear washbut when I operated the rear wash there was a sound of running water from somewhere so I stopped. Haven't used the rear wash for a few months now so tried again today. Operated the was hand heard the water sound again but kept it going and eventually saw water coming into the passenger wheel wel6under the glove compartment. Can anyone please offer some suggestions before it costs me an arm and a leg at a garage!!!
