I believe in Rain-X too! It's wonderful stuff and I would probably run without the wipers in place, but the challenge is to see this thing through. Had some time today and disconnected one wiper. Works and parks! Did the same for the other one. Works and parks! Ran them both together and saw that they were definately out of phase, but they did stop when shut off. BUT, one parked and the other didn't. Now if I used a diode, where would I place it and would this cause both wipers to park? Really appreciate the feedback.
