Thanks All!

At lunch I wiggled the wires around the fuse box and it worked for awhile and stopped again on the way home. As it began to rain, I noticed the wipers, high beams, and rear defrost were also not working! In the driveway, I got the systems to work intermittently with a firm slap to the top of the fuse panel. And by the by, I did a wholesale replacement of fuses less than 1 year ago.

I took the fuse box out last night certain that I would find a nasty mess of corroded and broken wires, but it all looked perfect and clean and dry. I also pushed and wiggled all of the relays while I was in there. I put it all back together and all is well so far. I did notice one of the screws on the relay panel cover was lose -- perhaps this was allowing the relays to work lose?? Don't know for sure but will repost if problem comes back.
