My turn signals would not cancel after turning. Sometimes I would not even notice because the car is so loud and the top is down half the time. Now it cancels perfectly and this is the fix:
Make sure the steering wheel is oriented in the straight ahead position. Remove 9 screws which hold the steering wheel. Remove nut with 27mm socket. Use a small gear puller to remove the steering wheel hub. Look on steering wheel hub for a small triangle(arrow). Point this arrow close to the turn signal stalk. Keep in mind the orientation of the top hole(for steering wheel orientation). Reassemble the hub and steering wheel.
