Need some help with wiring a light fixture, Light switch won't turn off light.

I had a fan in the room and I took it out and put up a dome light fixture. I can't turn off the light from the switch. The light is always on. I need some help with the wiring. I have attached pictures for reference. Any help is much appreciated.

The switch appears to have a black and white wire. If that is correct you have a switch loop. How many house wires not counting grounds do you have at the ceiling?

Heres some better pics

Coming out of the ceiling is 1 black wire, 3 white wires, and another cluster of 3 black and 1 white together.

I plugged my light fixture 2 black into the single black and the 2 whites into the 3 whites coming from the ceiling.

That actually sounds correct.

The switch does have a black and a white wire on it doesn't it? If so just as a test of the switch disconnect one wire on the switch and cap with a wire nut then turn the breaker on and see it the light comes on. If the light doesn't come on the switch is bad.

Here is what I think you basically should have. Note this diagram shows one black and one wire from the light but in your case it would be two. The recoding of the white wire black as shown in the diagram is code required but often not done as is probably the case with your wiring. Load 1 and load 2 carry power to other devices or fixtures.

Looking at the cluster of 3 black wires and one white wire..... follow the white wire to its cable. The black wire that comes out of that same cable goes to the blacks of your light.

The whites of your light go to the all white splice.

Test

Yes, there is 1 black, 1 white, and 1 ground going to the switch. I unplugged the white on the switch, capped it, and turned the breaker back on and the light didn't turn on.

Does this indicate that it needs a new switch?

Okay this is what I have.

3 sections of wires coming out and 1 ground

1- 1 black
2- 3 white
3- 3 black, 1 white

Are you saying that I should only have 2 sections of wires coming out? All black and All white? If so, do I just take the white and regroup with the other whites?

You've got un-needed piece of wire spliced in there.

Looking at the cluster of 3 black wires and one white wire.
Follow THAT white wire. It will go into one of the cables.
Coming out of that same EXACT cable will be a black wire.

Do you see that single black wire ? That goes to the blacks of the light.

To add to what Pete wrote: Sometimes it helps to think of cables not wires. Look at my diagram. You see at the ceiling you see four cables. Each cable has a black and white wire. I can't say for sure how many cables you have but I believe Pete is asking if you have a wire that does not go to a cable.

I unplugged the white on the switch, capped it, and turned the breaker back on and the light didn't turn on.
Then you should try a new switch.

It looked like the switch loop wasn't connected.
I'm surprised disconnecting switch had any affect on the light.

I took the white out of the group of 4 (1 white/3 black and capped it on its own. The light wouldn't turn on at all. I put the white back with the group of 3 black and the light turns on. The switch still does not work.

I forgot to mention that the fixture used to be a fan. The switch controlled the light but did not turn off the fan. The fan would still run while the switch was off, it needed to be turned of on the fan itself.

Hope that extra information helps.

It looks like in the ceiling there is 4 groups of cable (black and white) groups.

Replace the switch and see what happens.

The switch controlled the light but did not turn off the fan.
The fan black would have been connected to the group of black wire that also has a white wire and the group of other white wire.

What you probably previously had.

Your new light connects to where the fan blue wire previously connected. The fans black wire connection is no longer used. The neutral (white) connection is the same as it was for the fan.

Solved

Changing out the light switch and putting a new one solved the issue.

Thanks for all of your help.
