Root cause appears to be a material inside the relay causing the relay to stick after it was turned off. Production fix was implemented in May, 2004. Service fix is to replace just the wiper motor cover kit (P/N 88958372) rather than the entire wiper assembly (arm, motor, links).(04 Chevrolet All Full Size Trucks and Utilities) and (04 GMC All Full Size Trucks and Utilities) and (04 Cadillac All Full Size Utilities)
