Hi,
The wipers on my 88 Pontiac Trans Am do work pretty well, once they start. But they take 2 or 3 minutes to get going. Once they are working they still have a few quirks, but are usable. My setup has wash, delay, low, and high.
The high position works right away, but you have to wait for the low and the delay to work.
Any clues welcomed !!
Thanks
