Struggling with rear window switch issue.

Hey so my drivers main switch operates the rear two windows if you press the lock switch it stops operating the rear windows. So this is working just fine.

My problem is the rear switches won't operate the rear windows on their own. Only the main drivers switch operates them.

I've hooked the rear switches to the front passenger and they work just fine so the switch itself is good. I've tested continuity with the up/down pins to ground (See picture) which shows as good.

The power when the front switch is used to lower/raise the rear window reads at 0.69v and does move the windows albeit slowly.

What i have noticed is when i put the rear switch in to the front, i get 12v across all pins where as the rear i get zero reading until the front main switch is operated and then it's only 0.69v.

Is this a main switch issue, BCM issue or something else?
Front switches work just fine and operate all windows as they should, rear switches do nothing except stop me from using the front switch to raise/lower the window when someone presses on the switch while i operate them from the front.

The wire colour is from left to right.
Yellow, Red, Yellow, Blue, White. With the top pin being a thin black wire which i can't figure out what it does.
