Hello, I have an Alfa Giulietta, year 05-2012 2000 cc JTDM 125kw with a rear wiper that was not working, I found a broken wire in the wiring of the tailgate, I reconnected everything, checking that there were no other broken wires, now it works but it does not return to the starting position when I switch it off, but stops where it is on the body, and the error B1037 (rear wiper cam) remains, but I checked the wires again and they are all connected, could it depend on the wiper itself?
