Where to find answers on common car problems?

Are there any comprehensive websites to use for a car problem?

The driver side drl on my 2020 passat is out and I cannot find the hub inside of it for it. I think it is going to require some disassembly. Checked google and youtube for hours, something needs to come off for it. I poked around and pulled out the turn signal but there are no other capped holes accessible through under the hood or body cover which I removed to poke around. My dad is a car guy but he knows old cars, not newer ones. He helped me a bit but has severe macular degeneration and can’t see in there. I felt up everything and found nothing. I took a look at the module online and I think I might have located that which would need to be removed but a few things look like they need to be removed to access it.
