As stated above, my 1968 Corvette turn signals won't stay on unless I hold the lever. In other words, if I am turning left I must hold the turn signal lever down, and if I am turning right I must hold the lever up. The turn signal lever will not lock in either the left, or the right turn position. Also, I have a telescopic steering column.

Before I tear into the steering column, and knowing that the 1968 turn signal switch and canceling cam are different for the 1968 Corvette, especially with a telescoping column, I thought I would ask if anyone has had this problem before? Is it the switch? The canceling cam?

Thank you for your help.

I would bet it's the switch that has worn out.

Thanks toobroketoretire (me too btw) for the response. I am afraid you are probably right as it always seems to be in cancel mode... blinkers work fine just wont lock in position. After I tear it down I'll post.

As the turn signal switches are mostly made from plastic they wear out. I recommend buying a Standard Motor Products switch as they are the very best quality.

All I am finding is these interchange numbers 5698520, and D2662 (made in China I'm sure). As usual with 1968 it is a one year (actually 1967 as well) item. I went Standard Motor Products and it looks like they no longer make it. Supply and demand. Just have to buy the above.
Thanks for your help toobroke.

One seller on eBay said they used two different switches for that year, a red one- 5998520 made by Boyne, and a white one- D6226 which is a Delco product. The bolt patterns are supposed to be different, so I'll probably have to open it up first. I hope this is not true as I am only finding these numbers as interchange numbers, and the Boyne switch is common now.
Thanks

Does this switch look like yours? 67-68 Corvette Turn Signal Switch NEW 2121 | eBay
I googled "1968 Chevrolet Corvette Turn Signal Switches E-Bay" and found several of them but I don't know if they're the correct ones. You'll have to remove your switch and compare it to the pictures shown in the listings..

I am going to tear it apart tomorrow. I've never seen a car with so many electrical problems. I'll let you know what happens.
Thanks

Yes, that was the switch. The ears (actuators, I guess you would call them) are both broken off. Just have to wait for the part. Meantime my only horn started to work intermittently. Had a small car horn laying around, and it sounds wimpy now. Guess I'll find some new horns as well. I have the feeling this car sat around for some time- or maybe its just 52 years old. Fun.
Thanks Toobroke
