Hello,
My 2008 Ducato 3.0 motorhome developed a fault with the wipers whereby when on intermittent they would sometimes marginally pass the park position and fail. It did this twice and started working again after two minutes the first time and twenty minutes the second time, several months apart. It then failed for a third time and will not operate at all on any speed setting. I have measured the main positive and negative supply at the wiper motor five pin plug and 12 volts is present with the ignition on. With the wiper stalk at the intermittent setting I have 12V at the grey wire on the plug, and this is the case at the normal and fast settings. The other two wires have no voltage present at any setting. I believe one of the wires is to send a signal back to the body computer to let it know the wipers are in the parked position. Before I go ahead and order a new wiper motor I need to know if I have an issue with the body computer itself. I would have thought I would have gotten a 12 V signal present on at least another wire on the 5 pin plug. Can anyone help or does anyone have a wiring diagram of this part of the circuitry?
Thanks, John
