1995 Honda Odyssey wiper problem

Electrical problem
1995 Honda Odyssey 4 cyl Front Wheel Drive Automatic 200k miles

My windshield wipers are operational, but do not rest in the proper place when off and during the pause cycle in intermittent. They stop at angles across the windshield, right in the field of view. Could this be a relay issue? The wiring diagram shows several relays on the one-line, but does not indicate the physical location in the vehicle. Help me find them!
