Replaced both OEM windscreen washer motors which (in my experience) are prone to seal failure and leak washer fluid onto the floor.
Bought a pair of Trico aftermarket motors from the US. These are the exact same size as the OEM units and pop into place. I reused
the short motor harnesses/plugs to wire up the motors to the existing body harness.
For reference:
Front washer motor: chassis/body harness plug LG/B (light green/black) wire is Acc switched +12v, P (pink) is switched ground signal.
Rear washer motor: chassis/body harness plug LG (light green) wire is Acc switched +12v, LG/B (light green/black) is switched ground signal.
