Turning signal issue

As long as the signal is going off after the turn the cancelling cam is still working, the clicks are the lever that moves on the cam ratcheting as it passes it when the steering wheel is moving. I probably wouldn't change any of it until it stops working because, although it isn't that hard to change it, a replacement could be just as loud as it goes past the cam.
To replace it you need to remove the lower cover from the dash board. Then the upper and lower steering column covers. Next you unplug the switches wiring and then remove the two screws that hold the switch in place. The switch then slides out of the column module. Reverse the process to install the replacement.

If it does fail the most likely outcome is that you have to turn off the signals manually after turns so I wouldn't be in a rush either.
