DID the wipers continue to run with the w/w switch OFF, ignition ON, gray & black/lt blue pair disconnected from the w/w motor? Or did it run only when you jumpered the gray to black/lt blue?
Continued to run after turning switch off, leaving ign on, then disconnecting grey & blk/lt blu wires

Most common problems with these wiper systems are compounded or stacked issues. High resistance especially near or at the connector for the motor, the motor itself and connections at the module are the main points of high resistance. All it takes is a little bit of resistance and pinpoint tests become a cat and mouse game. As soon as you unplug or wiggle or backprobe connections the path of least resistance changes and the mouse moves to a new place. I would recommend repairing or replacing the pigtails at the wiper motor and disassembling and cleaning the connections at the module.
