My wipers had been going slow(on fast) if you know what I mean, for over a year. With the MOT comming up, me and my father in law spent 5 hours last Saturday taking the lankages out and freeing the spindles, which were totally seized up! Greased them and put it all back AS IT WAS --(very, very immportant!), and it's brilliant at last. MOT failed though on anti-roll bars, never mind! Just a tip though, when my wipers were letting me down, I used Rainex on the screen, virtually no need for wipers then---It's brilliant stuff! Jon
