The other thing is give all the contacts a good clean with electrical cleaning fluid and a kitchen scouring pad (not metallic they ...

Have you been able to check circuit continuity between the "B" pillar contacts and the door contacts when the door is closed ? I've heard of a couple of doors where the hanging of the door had been "adjusted" incorrectly which meant that the contacts didn't meet correctly height ...
