Brake lights are semi functional?

I haven’t tested the brake switch, and I believe that may be where the problem lies. Worst case scenario I will be replacing it as soon as possible.

So, after replacing the old switch, the brake lights still aren’t working. I tested continuity on the connection to the switch and found that the connectors top female ports do not have continuity. Does this mean I need to change out the wire harness?

Another note. I charged the battery, just to make sure that there wasn’t a low power issue.

Don’t have a probe like that, I have a CL120. But I’m getting tone indicators from all four points.

I’m changing out the relay for the brakes. Hopefully this is the solution.

Yes, I've tested all of the fuses for continuity, and they are all giving tone.

As of this post, here is what’s been done to remedy this situation. Testing tool used: Klein Tools CL120 Voltmeter.
1. Changed bulbs, and also inspected sockets, and tested for continuity: there is tone.
2. Changed and re-inspected fuses: tone from sockets and also new fuses.
3. Replaced brake light switch under dash above the brake pedal; tested socket continuity: there is tone.
4. Changed all but one brake/rear light relay (the sun was setting.) Unsure of how to test for continuity in this case.
5. Checked the engine fuses related to the brake or rear lights; no replacements made: there is tone.
Once again, the odd thing is that the top rear brake light bar is functioning, but not the two on the rear; And yet the hazards, reverse, and turn signal lights are all functional.

Yes, I tested both fuse and cable with the key set to on. There is tone on both.

With the key set to on, and the brake depressed, the socket is giving tone. The wires are black and green to the brake light socket.

Still the brake lights don’t work when brake is depressed.

Okay, so something interesting has happened. I was testing the ground for the taillights and noticed that one of the lights on the back of the vehicle switched to functioning as a brake light when the brake is depressed. So now the top bar and the passenger side bottom light is functioning as a brake light. The actual brake lights are still only functional as turn and hazard lights. Does this mean I need to change the connectors?
