Ok, as boring as it may be to talk about wipers, I have a problem with my delay wipers not working. The slow, high and off features work fine. But when I switch to anywhere in the delay/intermittent range, the blades stop in mid swipe. No washer function either (washer pump is new). It seems GM used an odd logic circuit board design which was only used from 1984-87.
I'm pretty sure this is the culprit, but no one sells these any longer. Anybody figured out how to repair these circuit boards or have one they could sell me? Wrecking yards have been no help. GM discontinued many moons ago.
HELP!!
