Wj 2002 Grand Cherokee WJ brake lights not working

I know there are threads covering brake lights already, but my problem is not covered in them. For a while, only the passenger side brake light was out, driver side assembly was fully functioning. I recently noticed, driver side is functioning except for the brake light, and passenger side nothing was working until I replaced the brake light switch. Now, the brake light on the liftgate works fine, but the brake lights in the taillights both don't work. The pass. sides running light works, but it turns off when the brake is applied. Here's a link to a video, so you guys can see what I'm talking about. Anybody have any insight? Thanks!

I am fairly new to jeeps but mine was having some weird brake light issues in the passenger side and it turns on replacing the whole brakelight fixed everything.
I think the circuit borad that the light sockets go into inside the tail light was faulty.
You can unplug the taillights and switch them just to see if the issue migrates with the light or stays that would tell you if its the light assembly or not at least.

If this is all just to newbish ignore me LOL I am not a mechanic.

I would try to check the connections that are in the taillight that touch the light bulb. I had the same issue and found out that prying up the connections works, seems like they get pushed to far down over time. I ended up putting a piece of copper under the connections. Hope that helps.
