Normally 'intermittent fault' is a bad thing, but I had a 'constant intermittent fault' - as in my wiper delay did not delay. I just took it off the car to examine the magic that makes it work - what a lovely device! Just a fantastic thing! First thought was I don't fancy my chances if that black hose that's buried in the wiring decided to leak - but hey, Rover would never use such inferior hose I am sure. Took it to bits, a quick clean up, some rubber conditioner on the diaphragm, some emery paper over the contacts, and a new bit of sponge to replace the dust that was my non-return valve, and my intermittent wipers are working as they should. I salute the designer of such a great gadget - I would have had no chance if this was electronic!
