- ML270 2003
I thought all was going well with my ML270, but it had to throw something else up. At MOT time, washers seemed to dribble, so took all apart, used a hose pipe to test washers, good fan spray, no blockage, but when connected again just about wet screen. It passed its MOT, but they are not right.
I have bought a new pump as my thoughts are its getting weak, but then thought.......
Is there a non return valve fitted somewhere between pump and first washer ?, i cannot see one, but most of pipe hidden.
Any one know ?
