Brake light and turn signal woes!!

[S1ck_WS6]

Ok so it started when I noticed that my turn signal would stop working when I applied the brakes, I then found that my driver side brake light wasn't working and assumed bad bulb.
Now 6 hours later and I have replaced every bulb on the back end plus the 2 front turn signals and cleaned each terminal and I am back where I started!

I'm loosing my mind, every other light works the signals work fine at idle but a few seconds after applying the brakes it stops clicking.

Here is a quick video, it doesn't show the driver signal as I forgot to show it but it does work.

yes, the main ground is inside by the trunk latch.

but the ground wires for the actual bulbs is the issue when the bird lights act up. I fixed mine by making a whole new harness. The sockets go bad themselves and power back feeds through other wires. It a common issue. A usual fix it to buy another taillight harness.
