Has anyone encountered the windshield wipers starting randomly...and you can't stop them? When they eventually stop...they stop in a random position except at their home position. Has this been encountered by anyone else and what fixed it?

I have a suspicion that the switch may be bad because when they go crazy, I spray some fluid to avoid them sliding endlessly on a dry surface. I got irritated and pressed the fluid spray a bunch of times rapidly...they continued running but returned to their home position after a few swipes.

Anyway, curious if anyone else has encountered this or if this is unique to my car.
