Found the problem poor design at its best
The warning light loom tie straped and running forward to the warning light cluster has mulitpul joints inside the sleeving just below the cluster, 5 green / brown wires joined in pairs then connect to one are crimped together and sleeved in heat shrink ingress of water has caused the joints to fail
at the same point in the loom there is a bunch of grey wires and 2 bunches of brown wires all done in the same way
quality heatshrink is linned with sealer so when heated it reduces in size the sealer melts and seals the joint against the ingress of water
