I know it's a long shot but any signs of water on the passenger side footwell! Just trying to help ya out!
It reminds me of the time I was trying to troubleshoot these hidden electrical  gremlins on my other car to later find out  there was water inside the PCM! 
I cleaned the contacts with some electronic cleaner and then let it soak overnight while applying some Wd-40! 
I truly understand you're frustration and been there done that,but try to not give up hope my friend! 
Btw try to monitor for any new Codes on a daily basis!  Z

There is a nut that holds them in place. You remove the nut use the puller to remove the wiper arm.

To reinstall just put the wiper arm back on its previous location, making sure it's lined up correctly and tighten down the nut.

The mount is cone shaped and splined.
