I've recently bought an E36 318is coupe (1995) and most of the time when I use the wipers, even when they come on automatically for windscreen wash, they carry on for ages. A good 40 maybe 50 wipes. Every once in a while they play nicely and wipe 2 or 3 times as they should, but it's quite rare.
Nothing I can do in the car seems to stop it. None of the fuses are gone, playing around with the wiper stick doesn't do anything. It's not such a big problem, but running your wipers on a dry screen doesn't do them any good.
Anybody got any suggestions? Is this a common fault? Google says no :(
