Dreaded Visor Droop Analysis

My driver's side visor had been drooping in the dangerous and annoying '45 degrees from the headliner' position for about a year now. Before I went and plunked 80 bucks down for another that would outlast the car, I gave one last try to try and make mine last with a durable repair.

Two screws hold the visor and hanger to the roof. After removing these and lowering the assembly, I find that the small wires to my vanity mirror light have been broken by the poor design of the snap on elbow that hides them in the hanger. Naturally, too close to the edge of the visor to splice them.

The hanger can be pulled from the visor and looks to be held in by a rubber donut that fits in the groove at the end of the spline. There is a flat space on the spline that holds the follower/tensioner device in the visor when it "parks" level with the headliner. This flat area had lost the bottom edge and therefore its ability to hold the visor level. Some loss in diameter of the spline was also evident.

I see no way of building up this plastic spline to proper dimensions with adhesive or other material as the stresses would just crack it off.

On a brighter note, I used a piece of 1/2" heat shrinkable tubing to cover the defective areas in the spline and carefuly twisted it back together. As of now I don't know why, but the visor is holding (after 1 day)!! If it proves durable, I have about 5 cars worth of tubing (for right visor, left visor, and 1 screw up) that I can send to willing others to test this.

On with the durability testing...........
