Servus, my Fiat Ducato 250 box van with 160 Multijet engine has a problem with the windscreen wiper. No matter what weather, when I turn on the windscreen wiper, it sometimes works and sometimes doesn’t. Often it is that when it runs from the very beginning, it suddenly fails. I then turned around at the control lever and so on, but it didn’t work. That’s why I let the lever on level three until sometime after a few minutes of the windscreen wiper starts to wipe. To say in summary that if the wiper works, I can choose all the steps. The engine also runs when it runs but I really don’t know what it is that the wiper often doesn’t work. Had jmd this problem and can tell me if it’s on the engine or relay, or k.a what?
