Directional Signal in 1963

[Gerald C.]

My directional signals in the steering column do not move smoothly nor do they operate properly.

When I use the signal lever, it is stiff and will not return to center when the wheel is returned to center. I've lubricated everywhere.

Also, this malfunction affects the rear lights/brakes. Could the cable to the switch on the column be causing this? Also, I beleive I have the steering column "bar" lined up with the column itself by the "dimples".

Any suggestions?

If I remember correctly that was a 1-year only setup for Corvette that employed a rather long shaft between the TS cancelling mechanism at the upper end of the steering column to connect to the switch at the bottom end of the column. Proper operation relies on the interconnect rod being 'true' AND the switch being positioned properly.

My memory says there was a very subtile adjustment for the switch relative to the control rod in terms of the attachment of the switch to the column...

Jerry,

This is a common problem for the 63's. The switch that is mounted on the steering column is usually the cause. After many decades, the slide in the switch becomes difficult to move and causes the problem that you describe. You can disassemble these and lubricate the moving parts, (not difficult) or, you can replace it. Original GM switches show up on ebay from time to time. (beware of the fake/aftermarket switches sold as NOS though. they are I.D. by the gold color metal. originals are silver/zinc)

Also, it's possible that the cable that runs down to the switch from the cam assy is stiff/binding in it's housing. That too can be lubricated.

While you have it apart, it's probably a good idea to also disassemble and lube all of the components of the cam assy under the steering wheel hub.

It's a strange system but it does work well when lubed and adjusted properly.

I also had major headaches on our 63 coupe when we first got it 2 years ago relative to the mechanism in the housing. I spent much time working on a malfunctioning directional before I realized my problem. The flat metal return spring was bent wrong and was missing the plastic roller. I replaced the spring and added the roller, and after adjusting properly has been hassle free since. The 63 Service Manual shows the correct flat spring and roller placement for reference. Check yours against the book and you may find it is not installed properly.

Another common problem is the slotted screw which attaches the ring(which the directional lever attaches to) was not tight. Because it was loose it caused intermittent action. I had to add a small washer under the base of the screw to get the alignment right. I also had to use some thread locker to keep it tight. Be careful not to over tighten this screw as it can strip easily.

Also, the canceling cam is made of plastic and often breaks. These are available and are simple to replace. It is mounted at the backside of the steering wheel so when you remove the wheel use caution where you rest the wheel. I always keep it face down.

I thought I had problems with the switch but it was never an issue in my case.

I might also add while it's apart to check for the proper alignment of the hub, shaft, rag joint and high spot(slash mark) on the steering box.

Update: My directional switch, when operated manually without the cable, only lights/blinks on the right side and when I move the switch in the opposite direction, the left side just lights up. But that position, to get it to light, is very sensitive. Is it time to remove and disassemble the switch for possible lubrication or should I just replace it.

Thoughts?
