What triggers turn signal cancellation?

[7Dcuda]

What in the steering column triggers turn signal cancellation?  I installed a new turn signal switch a couple months ago and everything has been fine.  Out of nowhere the left signal will not cancel.  Otherwise, everything else works just fine.  I took the steering wheel and crush can off this weekend to inspect the turn signal switch.  The cam is NOT broken and nothing appears to be obvious.  When I turn the wheel to the right, I can hear a click and then hear another click when the wheel is returned (i.e signal cancelling)  But when turned to the left, I dont hear the initial click when the wheel is turned nor a click when the wheel is returned. ( i.e. the left signal does cancel)  What in the column triggers the cancellation?  With the turn signal switch in place and operating you cant see behind it and nothing in/on the switch itself appears to be broke.  Whatever it is that causes the clicking noise when I turn to the right is my problem with the left side I just dont know what that is.

Cam inside the steering column.  One side is broke or not working.  Remove the steering wheel and can to take a look.  You can get to this part with the column still in the car, but the wire goes all the way down the column.

Ive already removed the wheel and crush can...the cam is not broken.

4Cruizn is right, lets take a look as some photos.  If it's not working, something is broke.  It's got to be in the column as that's the only spot where the turn single cam is.  I know you said it looked fine, but you asked and I'm saying it's broke in there somewhere.  Cam or what have you, it's in the column.

     Maybe the screws holding the cam are loose or broken. Is there a locating pin on the backside of the cam? I don't recall

The plastic part of the switch that releases the turn signal is very thin. Perhaps it is broken or cracked?

or the "snap" ring on the back of the steering wheel / crush can is missing

I appreciate the replies guys but my question still hasn't been answered.....which is..... "What in the column actually triggers the cancellation of the signal?"  When you turn the signal on you use the lever to physically operate/lock the cam to the on position.  How/what causes it to cancel when the steering wheel returns to the original position after turning?

the "snap ring" on the crush can has a leg that reaches down & bumps the end of the turn signal switch releasing it , if the snap ring is missing it will not cancel

Snap ring?  Are you referring to that fairly thick gauge coiled spring on the bottom of the can?  I dont see a true snap ring on the bottom of the can.  It was working fine though, cancelling in both directions until now.       

[Cuda Cody]

But wouldn't that stop it from working in both directions?  He said it works one way, but not the other.

yes the thick snap ring coiled under the bottom of the can , true it would not work both ways if the ring was missing , it was just another thought .

[Cuda Cody]

Neil has mentioned it, but it's the large snap ring under the can.  I don't think that's it as it wouldn't work in either direction.  It's worth a closer inspection to be sure while you have the can off anyway.
