Directional Off

How do i replace a directional switch on a Chevy Blazer?

I have a 2000 Chevy Blazer, tilt wheel 4×4
No cruise control
4.3 liter
Airbag

The directional switch needs replaced, do i need a steering wheel puller?
Is it possible to replace this at home without having the airbag go off?
If anyone has any info on this please answer.
Thanks.
