Okay I found the problem., The motor has 4 wires connected. There was a ground and power. However as I did not have wiring info, I pulled the motor.
Then I knew what wire did what.
Found that on manual once wipe, intermittent or low speed the 12v signal was sometimes there and not. Once I went to full speed and back to normal, the 12v was stable.
This led me to the wiper module relay (the long relay in the power box). I pulled it heard a rattle.
Opened it carefully to find on one of the relays, the return spring holding the armature, the looped end was broken.
I carefully bent up a new end and reassembled it.
All works perfectly!
Incidently the fast speed does work just in accessories position.
So not a wasted excersise as when I had the motor out gave him a clean up
