My washer pumps have given up on me! Took the scuttle etc off and unplugged the pumps to check im getting power, the one for the headlight washers is getting power but not working, the windscreen washers gets no power and the pump doesn't work either. One is full of water but neither work when conneted straight to a battery. Went to get another pump from the scrappies but every non clio sport seems to have a different pump and washer bottle setup?! Is this the case, do i need specific pumps for a 172? I took a pump anyway to check my wiring, this one works on the headlight washer plug but not on the windscreen one so need to work out why im getting no power to that aswell...
