Help with wall switch - Constant voltage


I'm trying to install a ceiling fixture light already existing wiring that's in the ceiling.

There are four wires total in the ceiling. White, Red, Black and a bare Copper ground. The Red and Black wires have constant voltage going to them even when I switch it off via the wall switch.

I took the wall switch apart and found that there's a Red and Black wire going to it and those also has constant voltage going to both wires even when I switch it off. I've already swapped the switch with a known working one and the same issue occurs, both Red and Black have constant voltage.

Anyone know what I should be doing to get this ceiling light fixture working properly? I can wire it up but it always stays on... I need it switchable from on and off.

Here are the pictures of the switch and the ceiling wires:




Any help would be greatly appreciated!

What was connected at the ceiling box before you started this project?

I believe it was a ceiling fan. Not 100% sure though.

you have something mixed up here. Your picture with the switches states two red and black wire. Is that right? Looking at your picture of the ceiling I see a red, black, white and green ( ground) Please clarify what is at the switches

Looks like you needs to pull the switches out of box disconnect all wire and check continuity of wires/ trace their paths.

How did you determine that the wires are always hot? If you used a digital meter it could be a false reading known as phantom voltage.
What happens if you connect a light to the red and white at the ceiling and flip the switch?
