Today I drove the car, and for the first time, it was misting rain when I had it out. The wiper blades on the car were shot, so I couldn't turn the wipers on. When I got back, I went to the store to pick up a new set. I put them on, and got in the car to turn on the wipers(2 speed wiper motor). This is the first time they had been turned on it probably 27-8 years. The wipers would go all the way up then stop on low speed. I turned it on high speed and they would do nothing. Then, I could turn the switch back to the slower speed, and they would go back down, but not all the way. I did this about 5 times, but I never could get them to work consistently. When I replaced the engine harness, I replaced the wiper motor harness too. Does the problem sound like an issue with the wiper transmission? It sounded like something was scraping/rubbing when I had the wipers turned on. Could it be the motor? The wipers were extremely slow about moving up and down.
