Tl;dr this alternative mod is working really great so far. The visors snap all the way up.
Hi! My 2019 van’s visors have been floppy since I began using it (6k miles at that point, 40k now). They’ve gotten progressively worse to the point that, if I were to lurch forward in a crash, they could scalp me. I’m very tall. 🤷♂️
I studied these magnet- related posts - thanks! - but in the end decided the spring mechanism itself is maybe ok (it’s still very torquey, tough to actuate by hand once you disassemble the thing from the car) it’s just the structure that was trying to hold it in place that was inadequate. I think it’s some kind of sandwich attempting to squeeze on either side of the mechanism, but which is easily popped apart by typical road conditions. I decided to try to squeeze that sandwich back together and see how it worked.
It’s very easy to take the assembly off the car, T20 is the size bit or wrench needed. This would be annoying to try to do in place.
Here’s the hardware I used. I have it on hand because of a product my little company makes. Half of it is a binding bolt, female end, the other is an off the shelf button head screw and washer. There’s room for improvisation here. There’s adequate space above the closed visor for a nut (or lock nut if you want to be vibration wary). You’ll want it to be about 5/8” when cinched up but it’s best if you can get the parts to engage at 3/4”. I’m sorry I didn’t take measurements while I was doing it.
Another important note: I did find a _wrong_ place to put these fasteners. I thought I was going to put two sets up there, you can see the marks on the blue masking tape. But the holes I tried to drill that were 9 inches from the mounting end wouldn’t go through easily. I think there were steel components there (Spring steel for the mechanism?), while in the other location I was just drilling aluminum & plastic. It seems to be working great with just the one set though.
Also, possibly helpful: I started with a 1/16” bit and drilled through with masking tape on both sides in order to know where my holes were going to meet up. But then I used a razor knife to cut the vinyl on both sides before drilling with the larger diameter drillbit (0.206 for my fasteners, YMMV). I was worried about the vinyl twisting and making a mess. And then on a subsequent hole, I decided I was being overcautious. I tried drilling the vinyl, and it twisted and made a mess!
Another random note: if you can have a strong shop vac pulling right where you’re drilling it might help reduce debris. It gets trapped under the vinyl. I didn’t use vacuum and there is debris sort of showing lumps from inside the vinyl. But it’s not bad and it’s not as disfiguring as the droopy visors.
It really does seem to be working well, feels solid and they snap right up quite firmly. I need to go back and put some Loctite on my fasteners.
Let me know if you have questions. I’ll keep you all posted if it stops behaving well.
