The sun visors on my 1975 Buick LeSabre convertible keep falling down when I want them up. I’ve tried the following:
- I bought some GM plastic inserts ( GM part number 12337899) that go between the rod and clamp. They improved the tightness a little, but not enough.
- Tightened the clamp screws to maximum on the visors.
- I’ve tried stuffing other materials, like zip ties, paper, etc. between the rod and clamp.
Right now they have new GM plastic inserts because of all the things I’ve tried, they seemed to work the best. But still they fall.
Does anyone have any experience with this problem and a fix that works?
