I finally took the time today to tear into the drivers side sun visor. For about a month now, the drivers side sun visor has been able to stay up in place but there is no adjustment except for straight down when I'm trying to use it. It's extremely annoying and keeps me from seeing what I need to see!
I had a very small amount of time to fix it so I don't have any pictures yet. The passenger side visor is doing something similar except it's not staying up but has adjustment when down. I'll fix it the same way because I think it's only a matter of time before it too has no adjustment while down.
The pictures posted in PaulS's gallery are very blurry and lack intimate detail. I used his pictures as inspiration. Basically, you have to tear apart the entire upper portion up to the point in his pictures. He's showing the drivers side visor so you need to tear apart the upper left third of the visor to fix it right.

When you tear into it, use a seam ripper to undo the threads closest to the area where the sun visor screws into the ceiling. The adhesive that holds together the rest of the fabric easily separates. After that, you need to remove all of the foam around the arm and mechanical mechanism to expose the entire sun visor adjustment mechanism. You'll have to remove some extremely annoying adhesive tape from both sides of the visor. The only way to remove the adhesive from your hands is acetone! I tried soap, rubbing alcohol, etc. I just said to heck with it and used acetone on a rag. After removing the tape and foam, you'll easily see the hole that already exists. This is where PaulS shows where he put in a screw. Putting a screw into this hole will allow the sun visor to stay up in place when not in use.
If you have the other issue with the sun visor dropping straight down, you need to install 2 more screws. They will be to the left of the hole that PaulS referenced. However, you will need to drill 2 holes to put the screws in. I will post detailed pictures of these later. Bottom line...I used 3 size #6 hex headed screws, 6 locking washers, and 3 standard nuts to tighten up the sun visor mechanism. After drilling the 2 extra holes, just insert the hardware, tighten and you're done. The tighter the screws are, the harder it will be to adjust the sun visor. I adjusted them and did multiple tests until I found the perfect amount of resistance. It doesn't feel anything like OEM, but at least it works perfectly!
I'll be taking care of the passenger side visor sometime this week. I'll take detailed pictures and post them here. Hopefully they will help someone else forgo spending a ridiculous amount of money!
