So I got the mechanism installed. It took about 6 dry fits before I was happy. The passenger side shaft sticks out of the cowling about 1/16" more than the drivers side. On the inside, the nut and washer on the drivers side wiper shaft, isn't exactly flat with the fiber glass. The passenger side is pretty close. I don't know if this is going to matter yet.
I grounded the two brown wires and supplied power to the red one. I wrapped a piece of wire to each of the wiper arm shafts to simulate the wiper arms, and turned it on. This unit wants to nest on the right side of the car. It did also seem to struggle while it was operating, like it was binding. The motion wasn't smooth. Not sure what to think of that. Maybe it was wired backwards and the mechanism doesn't like that direction???
The way it's wired, it seems to want to get power from the ignition switch. I initially touched the red end to one of the red posts on the ignition switch, and when I turned on the wiper, it shorted a 30amp fuse in the fuse box. Maybe due to the binding? This is when I supplied power from a different source for testing.
Well I'm tired of laying on my back with my head under the dash for now. Just wondering what your thoughts were?
