I HOPE that in your photos...your front wheels are pointing straight. THIS IS A MUST!!!!!!!...and NOT just getting the notch to the 12 o'clock position and your front wheels are turned.

IF your front wheel are pointing straight.....YOUR COLUMN is CORRECT and here is my OPINION WHY it is.

I can clearly see the notch in your center shaft for your 'tele' function. And this notch in the end of the shaft is at 12 'o'clock'. AS far as I know....that is correct and always where I have it positioned when working on the column.

I recently worked on a tilt column where the notch was at the 6 o'clock position when the front wheels were straight. AND this was due to the previous mechanic who messed with column column. At the universal joint coupling down in the column where it allows the shaft to tilt. It must have come apart and when the person reassembled it. They put it in upside down. So...when I took the column apart and corrected it..the turn signals worked perfectly.

Also...when you look at the backside of the horn contact , You will see that the two notches are located in between the two spring of your turn signal switch...which is ALSO correct.

There should be NO reason why it is not working correctly...IF your wheels are pointing straight...AND your notch is at 12 o'clock ...especially if you also install the lock plate and get the clip installed.

Did someone replace the steering column coupling?

If the column shaft was installed incorrectly with the hash mark wrong this could be the issue, but looking at your pictures it seems to be okay. So the only conclusion I can come up with is that possibly you have one of the china reproduction steering coupling flanges where they were 180 out... and when you have this you have the exact issue you state. The vendor that made them didn't seem to care either, they just kept selling them until they ran out. I've got three in stock right now that we got hung with because of this.

Check to see if it looks new and post back.

That the wrong coupling can change how the notch at the end of the column shaft changes it position when the wheels are straight forward....THUS...changing how the turn signals cancel.

But if the front wheels are straight forward...and the notch is at the 12 o'clock position..the turn signals have to cancel correctly.

It all looks correct, even if the wheels are not straight in relation to the pics, it would still cancel, just have to turn the wheel more. Have you tried changing the turn signal switch? and can you make it cancel by tripping the cancel spring without the cam in place?

The turn signal switch is correct and is NOT the issue. The springs in it are correctly located so the cancel tabs on the back of the horn contact will do their job correctly.

YES...the turn signal will cancel no matter what position the front wheels are pointing...but to get the turn signals to cancel correctly..the front wheel MUST be pointing straight forwards and the notch in the column shaft at 12 o'clock.

Understood, the op said it will not cancel at all for the right.

My previous post was directed to the OP, this post is directed to Dub.

they are pointing straight ahead. Just sentered the box and the steering wheel is not straight a head ,I will move the
tie rod ends and get the wheel pointing straight ahead ,indexed at 12 o'clock and I hope it will cancel. Does this make sense?

Is the left turn the same as the right turn?

You will KNOW for a FACT that you have your center link for your steering correctly centered...is when you look from the front...and the INNER TIE RODS GREASE FITTINGS can be seen EQUALLY from one side to the other where you use your lower control arm as a gauge. The grease fittings should be visibly the same...and where you can use your grease gun on each side and not have to turn your steering. IF that is correct...then you KNOW your center link is centered....and then you check your steering column shaft and then adjust your tie rods ( if needed) to get the wheels straight.....and that is ALSO assuming that the rag joint or steering coupling is correct also and not throwing everything off due to being an aftermarket piece of crap....which ( unless they have corrected the problem) are not clocked correctly.
