Main power window board not working!

Hey, as stated the main window power board isn't working. All other windows will work but the drivers 1 wont and the board wont.. I've changed the Relays and still doesn't work.. I've checked if its getting power and it seems not to be but the lights on the switches work but assume that's a different power source.. Is there something I'm missing? Like a dud earth or something? Where is the earth for it? This is in my E39A.. Everything's in Japanese which makes for more fun!

Earth means ground . So check if you have good ground connection with them your circuit is incomplete.

I had a problem with the plug in between. It was just one of the wires so I had to jumper around the plug. Same exact problem you are describing.

Is the passenger side window switch plugged in? From memory the drivers panel wont work if the passenger side switch isnt plugged in.
 

Where is the 'ground' for that? And yeah the passenger window works, all the other windows work on there own switches but that main board won't..

Wait. I could roll my other windows down from the main board, but not the drivers window. Hmmm.....I think the ground is under the dash and comes through the plug for the door harness. I don't think it's in the door! If I remember correctly the power is a red with a blue tracer.
