Thanks for the reply - 3wbdriver.
The momentary function has the same issue (and is actually the most aggravating)
So the issue appears to lie in the "OFF" position - likely a cracked or faulty contact at that position. If I manually nudge/tweak the wiper stalk while in the "OFF" position, the wipers do return to their resting position after wiping from any method (Momentary/Intermittent/Low/High and even when using the sprayer from the "Off" position).
I don't have a lot of free time these days, so I'm not looking to troubleshoot too intensely if I'll just need to replace the stalk in the end. I'll round up a few stalk prices and go from there unless anyone thinks this could be fixed rather easily.
So I assume no one here has ever had this particular issue?
