I am having trouble with the headlamp washers on my W209. Sometimes they both work, or one works but not the other one, or neither will work. I suspect the pump is on the way out, I have a pump in stock ready to fit. I can't see it being a jet problem as they both sort of work but not together. The pump change is easy enough to do, but if I do need to change the jets I think its bumper off again or can I get to rthem by just removing the under tray.
