Crazy Wipers

[Yetti]

mine have " gliched" a couple of times. once it was on high and didn't want to shut off after turning the wiper to "off". another time the delay was going along fine and I bumped up to Low and it just stayed in delay, once I cycled the key off it was fine. hasn't done it in months.. I would suspect its a issue with input signal from the switch on the colume. I have seen other GM products do simular stuff. the biggest issue on the older stuff is the "Park switch" it goes bad and won't sence the bottom of the stroke so as to stop the wiper trans in the right spot.
