I had the same thing - it also affects the 4 way flashers.  you'll end up replacing the entire control arm (turn signal lever)
Good luck!

SOURCE: how do i remove it

your turning signal flasher is in one of 2 places either under the hood where it would be clearly marked or under the dash in your fuse box ,it is a big black round or square fuse or relay once you determain where it is you just pull on it and it will remove. good luck

You may look or feel the back side of the steering wheel, looking for 2 screws that hold the airbag to the wheel, these will be internal torq type screws (star) you may have to rotate the steering wheel 90 degrees to access the screws. You should first disable the airbag, by removing the airbag fuse, and or by disconnecting a yellow connector located near the base of the steering column. under the knee bolster.(panel below column). Once the retaining screws are removed, lift bag and disconnect the 2 connector to the airbag, the ground for the horn, and the horn contact wire, which requires you to push down and twist counter clockwise, damage to the horn contact ring will occur if you try and just pull connector from the ring. Now you can remove the steering wheel, may require a puller, and the you will have access to the turn signal switch.
