Turn Signal Switch

I'm almost a hundred percent positive that my brother's turn signal switch is bad. When you put the right turn signal on it's like it shorts out and the dinger is there but no signal. When you lift it up just b4 clicking it on the signal works. My realy question is do i have to pull the steering wheel off to be able to remove this?

I figured that, I just wasn't sure about the steering wheel. I didnt one on my 93 grand am that i was supposed to pull off the steering wheel but i just broke the plastic pieces and you can't even tell.

Except i dont wanna do that to my bro's mustang lol
