Thread: GM style column - turn signal issue

Tweet

IYou will have to pull the wheel and the locking ring. That is held on by a small wire clip in a groove on the steering shaft. The hard part is that the heavy spring under the locking ring has to be compressed and held to remove the locking clip. There are tools available to do this. I have done it without the tool using a big friend to push down on the locking ring, but I highly recommend the tool. Trust me on this. You will also need a couple of picks or very small flat blade screwdrivers to remove the clip, which a round wire affair.

Once the locking ring is removed, you can access the cancel cam and horn ring(same part). The snout that the horn wire attaches to needs to be positioned at the 10:30 to 11:00 clock position to get the signals to cancel properly left and right. Check out the ears on the cancel cam to make sure they are not worn. Aftermarket replacements are available, but I prefer to use genuine GM parts when possible. Some of the aftermarket parts have quality issues.

On hot rod installations I have ran into the problem of the slot in the locking ring not allowing the cancel cam to index in the proper position. The locking ring is splined and there is usually a dead spline that will only allow the locking ring to go in only one clock position. I have had to file or mill the cancel cam slot larger to allow the cam to index at the proper clock position. Nothing holds the cancel cam in place but the spring pressure.

Not a fifteen minute job, but this is the only way I know to do it. You could also adjust your tie rods to reposition the shaft and then pull the steering wheel and reposition it, but I don't really like that. I have the spring compressor tool and can do it that way much quicker. Just had to do this on my Healey the other day.

This is the tool:

Edit: Roger types faster than I do!

I should also add that the steps I mentioned were for a stock GM column. Aftermarket columns are similar but some of the internal parts are slightly modified. Still basically the same procedure.
