Hello all - if you are still out there.

OK - have so far proved I have no constant live at the motor plug. Swapped the REC. Tried another wiper motor anyway. Swapped the CIM back to another. Swapped relays in UEC.

To bear in mind with this, I have still got the imtermittent fail of power steering on start. To that end the UEC, ECU and SIM were previously swapped out.

Could it be the BCM - about the only thing still left in the canbus apart from the door modules !
