Drivers side is ok, I have a complete loom spare that I have familiarised myself with and powered up and all works ok.
I have swapped switches and the relay and there is no difference.
I ended up just applying 12v and earth to the yellow wires on the passenger switch, to get it up and tackle later.

This is no place to be talking about 'tackle' and 'getting it up' Al

The loom for the windows has its own fused relay and is powered a 12v fat red wire, the relay is powered by an ignition live pink wire, so there is power 
2 red/black wires go to both switches, there is an earth return for the relay and an earth for the driver side switch.
The driver’s side switch has 6 wires
green/black = drivers window down, goes to drivers window motor
green = drivers window up, goes to drivers window motor
blue/black = passenger window down, goes to passenger switch
blue = passenger window up, goes to passenger switch
red/black = power from relay
black = earth
The passenger has 5 wires
yellow/black = passenger window down, goes to passenger window motor
yellow = passenger window up, goes to passenger window motor
blue/black = passenger window down, comes from drivers side switch
blue = passenger window up, comes from drivers side switch
red/black, power from relay.
There should be 12v on the passenger yellow wire when the passenger up button is pressed and 12v on the passenger blue wire when the up button is pressed on the drivers switch. The 12v is not there.

going to do a continuity test and resistance test if there is no break in the wires. Waiting for a dry day as I may have to replace the loom.

Hi...
Had a very similar problem with mine...
The wire was broken in the driver door, were it exits the door and goes to the A-pillar.
Hope it helps
