Hello and welcome to JustAnswer!
The multifunction switch on your car isn't hard to remove.
Start by removing the steering column shrouds. There are screws up from the bottom side and then the shroud halves will unsnap from each other.
Once the shrouds are off you'll see the switch. Unplug the electrical connector and remove the two Torx screws that hold the switch to the steering column, lift the switch straight up to remove it.
The combination flasher is on the back of the switch and won't come with the replacement switch. Be sure to swap the flasher over to your new switch before installing it.
