Now that I got a nice new working switch I can get wiper action... the problem is that it is intermittent wiper action. I checked with a multimeter and I am only getting about 10.5v through the pink power wire in the back. I traced that wire as far back as I could go, but I didn't find where it goes. Does it go to the fuse box? If so, would it be possible to completely replace the wire with a new one? Anybody done that?
