So, I wanted to finish off this thread to some degree. I replaced the ignition switch (small black unit that turns when you turn the key) but that didn’t seem to fix the issue. My drivers door lever mechanism again broke so I had the door apart and the master switch out. Opened up the master switch but could not see any water ingress issues. After putting it all back together and the door back together with a new handle mechanism I haven’t had a window issue since. By the way, I read elsewhere on how to correctly open the door and give the mechanism maximum life span.
