Based on the wiring schematic the front washer and wiper system is not linked to rear.
What happens if you turn ignition off nad then on again? Does the wiper move? After resetting by turning wiper on, does the problem occur immediately when ignition is turned off and on again?
Check for a poor ground circuit for the rear wiper motor.
