Running out of swear words

I'm thinking that there must be some junction up under the dash where air wouldn't get to, where all the big green wires for all the doors join the power source and then another color of wire continues to the BCM,(maybe brown), I don't know now whether to scrap the BCM to see which output the PWR win fuse is connected to,,,, or pull out the whole dash to see where the green wires go,,,

Junction?

The 4 green wires that power the 4 individual windows must join somewhere before going to the source of power,,,,, Does anyone know where that is?

The green in the doors is the same gauge as the red wire with the black stripe that's above the green in your pic

Sorry.
I have scoured over these schematics I have but they're not user friendly. Not in order would be a better word.
The green wire I have referred to that goes from the main switch to the BCM. The schematic shows the BCM, 2 amp fuse and RAP(retained accessory pwr ?) I can't for the life of me find where it connects to a relay.

And no, I'm not tearing mine apart to try and help you.

Well, thanks for tryin!! :) the only wire on the whole BCM that I can find that's the same gauge as the green wire in the doors, and only has power when the key is on, is a big brown wire on the back of the BCM in a big white plug..... I tried taking the top off the dash to see if I could follow the wire but apparently u require a fire axe to get it off! Lol

Sorry but no more fire axes for me. I retired 3 months ago.

Keep us updated on anything you find. I'll do the same if I come across anything helpful.

Well, I got the top off the dash,(sans axe), however, it's covered under that so that didn't help at all... Appreciate the help! :)

OK. Found a little more in the schematic.

Window switch wire goes to the Power window fuse.(30 amp)
Power window fuse wire goes to the RAP relay fuse(50 amp). This is apparently in the wiring harness near the battery.(according to the schematic wording of location)
The RAP wire shows to be a Red/Black wire going to the BCM.

Unsure of the wire color from fuse to RAP.

RAP: Retained Accessory Power. Ex: How you can still roll the windows up/down after the key is off.
