Just to let people know,
A week or so ago after being jammed with snow sliding off the roof my wipers would not park or work on delay. Someone on this list suggested that I pull out the delay relay from driver side kick panel, open it up, and look for a burned trace on the PC board.
Well that was exactly the problem. I soldered a wire across the burned trace, put the relay back in, and the wipers work great now.
