Thread: GM style column - turn signal issue

Tweet

I have an aftermarket GM column in my Fairlane. The left blinker works fine, the right works, however it cancels with the slightest turn of the wheel. Is there an adjustment to correct this?

Is this a tilt column or standard? I'm not sur eif there is an adjustment but the cancelling cam my be up too high or the arm could need adjusted to hit it in the right spot?

I still have the same problem on one of mine, and it has to do with the position of the canceling cam arm when the wheel is installed. From Flaming River's FAQ's:
Q: How do I set the cancelling cam to get my turn signals to operate correctly?

A: The canceling cam has two functions: First, it acts as a contact for the horn. Second, it cancels, or turns off, the turn signals as the steering wheel comes back to the straight-ahead position.
When the canceling cam is not clocked or timed correctly in the column, the turn signals will not cancel, or they will cancel too quickly. To properly clock or time the canceling cam, you should look at the top of the column like it's the face of a clock. On the canceling cam itself, there is a stem that sticks up approx 1-1/2”. Imagine this stem as the hour hand on a clock and place it at approximately the 10:30 position. This will ensure that the turn signals will cancel every time.
If you need additional help, please refer to this article or these videos — non-keyed columns or keyed columns.

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.

One of mine is an IDidIt tilt column, and one is Flaming River tilt, both "GM Style" and both floor shift, no column shifter or key. Neither has the locking ring you describe. Once the wheel is off the horn contact/turn signal cancel ring can be lifted out and clocked, then the spring, wheel & nut hold it all in place. Sounds much easier than stock.

UPDATE: I didnt need the special tool. The cancel ring was located at 12 o'clock. To move it to the 10:30 position I had to remove the aftermarket steering wheel from its hub and repostion the hub. Works pretty good now.

Thanks for returning and letting us know the solution. Many of us are "completists"... we like knowing the outcome.8-)
