Well, I fixed it. Seems that its brain got scrambled somewhere along the way while AI was working on the wiper/washer problem.
The fix was: I disconnected the battery for about 2 minutes, reconnected it, and everything is fine.
I have to tell you, I was really worried that I'd somehow ruined the Ignition Control Module ($1200). I can't tell how relieved I am that it wasn't.
Thanks for your earlier response.
