I need some help. Sun visor lights, on both sides, stopped working on our 2019 Q7. No other issues, all other lights inside the cabin work fine. The fuses all look good.

Both sun visors' lights stopped working after I had the windshield replaced.

The glass place claims that they have not touched anything related to the sun visors. Any ideas about what and where I should look for? Are any connectors responsible for the sun visor lights only? I did not see a fuse responsible only for the sun visors.

Thank you!!

Audi calls these Vanity Mirror Lamps and they both share a "Ground connection (in roof wiring harness)" and a wire to the J519 module via "Connection 1 (in roof wiring harness)". I would take the housing off the interior rearview mirror and check for loose connections? Alternatively, you can pull down the overhead console just behind the mirror, if your fingers are strong enough, there are ground connections to the roof there.

Wiring diagram (for 2017 PP+ at least), show no fuses on the circuit.

BTW, do the glove box and footwell lights still work? (Also connected to J519, but different grounds)

The light in the glove box works just fine.

The footwell lights work, as long as the headlights are on.

Do you have access to a wiring diagram? If yes, do you know what color the ground wire is? I suspect that's the issue but i won't be able inspect before tomorrow. If i know the color, it will be even easier to locate it.

Thank you!!

For Q7 2017 Vanity lights:

Fixed. I had to remove the overhead console and I quickly found a wire with a brown connector that was NOT connected anywhere.
Traced it and the wires were the same color as the wires connected to the visors. After some digging, I found the other wire with plug that these two pieces had to be connected.
I connected them and it All works now.

I have zero idea how, why, and when this wire got disconnected. The windshield replacement guy claims that they never touched that area. I had a body shop work on my car 6-7 months ago, but they also claim that they have not done anything there.

I am glad it's all working now and it was a simple disconnected link.

Thank you for your help and guidance!!

Thanks for posting this wiring diagram!
I need a new connector and the terminals that plugs into the passenger visor but I cant tell from this diagram which connector type goes to the visor. Attached a couple of photos for reference.
