R26 Rear washer pump not operational.

Evening folks. My Megane R26 dual washer pump died. A new unit has been installed and before installation, both polarities were tested. The front windscreen is now functioning. But the opposite polarity for the rear, isn’t. The motor does not even sound.
Is there a bi directional relay for the Megane in regards to the washer jets or is it controlled purely by the body control module?

Prior to failure, both front and rear were functioning.
It would seem as if the stalks sends signal as when the rear jet twist function on the stalk is operated and held, the headlight jets operate.

Any insight??
