I've replaced the washer pump today after a problem with the windscreen washers and the warning light coming on. The warning light has been extinguished by the new pump, but I'm not getting a drop of water through the jets. Before I replaced I was getting a small squirt that didn't quite make it to the windscreen. The rubber bung that the pump sits in is as clean as a whistle and the container is free of gunge. I can only think it must be an air lock or a blockage in the pipes leading up to the bonnet. Any suggestions welcome. I read a good blow through with an airline may cure it, but I haven't got an airline, or know how to do this??? The Rover is due for its MOT and this is an instant fail. If nothing forthcoming I may have to bite the bullet and take it to my garage, which is annoying and probably expensive considering that any garage will charge at least an hour's labour.
