Windshield Wipers

Here's a short video which shows the operation of my wipers I'm finishing installing. The biggest challenge was putting all 3 wiper motors on one switch with a momentary bypass to allow me to clear spray off the windows. The motors mechanical self park switch kept backfeeding the other motors so they would keep running in the off position until all 3 internal switches were in the same position finally allowing them to stop at the same time. Adding a couple of 5a diodes into the circuit stopped the backfeed and would allow each motor to self park on their own! Problem solved.
