Hello! so I have 1998 mustang gt convertible and I have been dealing with this problem for some time now, my windshield wipers are stuck on, on the highest mode, occasionally when they are on (not often) they’ll randomly stop then go back to being on. So my short term solution has been to unplug the fuse. All my blinkers and headlights work. Any suggestions? I’ve previously had to replace the whole ecu on the car, but even with the old one, the wipers did the same thing.
