Bath fan working, but not light

Hello all. Have an issue with new bath fan light not working. The old fan did not include a light. The bath vanity light fixture works, but not sure if it is causing the issue.

There are 2 switches in bathroom. 1 switch to bath fan. Has 2 black wires and 1 ground coming off of it. Both black wires on right side.

Other switch has red wire on top right, and black wire on bottom right side.

Wire in ceiling has white, black, and ground. The bath fan has blue and white for light, and black and white for fan. Blue and black are connected to black. White and white to white. Fan works, no light.

Vanity light is hooked up as: red wire to black wire on fixture. White to white wire. @ blasck wires are capped off in box.

My guess is the wiring for the vanity light is causing the issue for the fan light not working, but I don't know enough about wiring. Also can't wrap head around why the fan would work, but not the light if they are wired together.

Any thoughts?

Thanks

I was going to say it's the vanity wiring also, but the fan works.....

Do you have a meter to check for voltage? It might be just the bulb or a bad connection at the blue and black wires.

I don't have a meter. Dad is coming tomorrow if I can't fix by then and he has one. Actually this is the second bath fan light unit where the light doesn't work. Remodeled the bathroom 2 years ago with new fan, light never worked. Bought new fan now and light doesn't work. Super strange.

@ blasck wires are capped off in box.
So they are not connected together, is that correct?

The 2 black wires for the vanity light? No they are just the 2 of them with a wire nut. I was wondering if the 2 blacks (or 1 of the blacks) need to be with the red.

Are you trying to put both the fan light and vanity light on one switch and the fan on the other switch?

Does power come in at the switch box?

Does the 3-conductor cable go between the switch box and the vanity light?

Are there two 2-conductor cables and one 3-conductor cable at the switch box?

No. I would like the bath fan/bath light on 1 switch, and vanity on another. That is how it was originally working. I have a feeling that when the vanity light was replaced 2 years ago, it didn't get rewired the way it was. And that is why the bath fan light isn't working. Let me look again at the wiring.

Wire in ceiling has white, black, and ground. The bath fan has blue and white for light, and black and white for fan. Blue and black are connected to black. White and white to white. Fan works, no light.
That is correct wiring if you want both fan and light on same switch. There is no way fan is working, but not light.

Undo wire nuts is make sure insulation on the wires are stripped and connected securely.
Also check the lamp and lamp assembly is plugged.

I'm telling you for a fact the fan is working, no light. 2 different fixtures, same story. That is why I'm so confused. The old unit had 2 bulbs neither lit up. I put 1 bulb in the new one to see if it worked. Nope. As of right now, the fan is laying in the attic. I'll go buy a new bulb and try it.

Ray- In the box there are 2-2 conductor cables and 1 3-conducter cables. 1 of the 2 conductor goes to the attic for the bath fan, and 1 2 conductor and the 3 conductor goes to the vanity. In the box for the vanity light, the 2 black wires are connected together (not with the fixture). Only the 1 red and the white is on the fixture.

So thinking about it, in the switch box 1 of the conducters is power in. 2 out. So I'm thinking now that the conductor in the attic is coming off of vanity light box? Right? Maybe the light in the bath fan is not working because the blacks are not wired to anything in the vanity box?

Just a bit of terminology to avoid confusion. When you write conductor in your last post you mean cable. Correct? A conductor means a wire but you are writing of a cable, two or more conductors (wires) in a metallic or non metallic sheath. Correct?

Therefore when you wrote:
in the switch box 1 of the conductors is power in. 2 out.
You really mean you have only two cables, not three cables. Is that correct? You believe one of those cables is power in and one cable is power out. Is that correct?

Using a multimeter, preferably analog, test from each black in the vanity box to ground or neutral. Does one show about 120 volts and the other none? (A non contact tester can not be used for this test.) If so try connecting them together.
