It seems to be pretty common for the Turn Signal switch to stop canceling after a turn. Nowadays the turn signal switch can be replaced without having to pull the steering wheel. The switch itself isn't fairly expensive and can be purchased from amazon for less than $30

First I'll outline removing the old switch, Replacing the new one is just the same steps in reverse.
Then I'll point out the weakness in these switches.
- 7mm Socket/Nut Driver
- Flathead Screwdriver
To make it easier, tilt the steering wheel as far down as possible, and pull it as far out as possible:
Now to pop off the top cover. It just snaps on, I found it easy to grab it by the edges from each stalk hole and just pop it up:
Once open you'll see all the wires and switches, Amazing how much crud settles down in there:
Next you'll need to remove the lower cover. It is held in place with 3 7mm bolts.
Once the bolts are removed you can either just let it hang, or wiggle it out. It's not too difficult to get it passed the tilt lever:
It's also worth noting those bolts are screwed into plastic, When it comes time to replace everything you don't need to tighten these down very much. It's just a plastic cover after all.
Now the switch is held in with two clips only. One on top, one on the bottom:
You can just take a screwdriver to each little opening and push them inward to release the clips:
