Horn Switch

[dannyboy20]

Ok I have a 98 GMC Sierra and the horn works occasionally. I have determined that its the switch in the steering wheel. However I canot get access to it. I have tried a couple of different times to remove the airbag bu I cant get at it. Is there some kind of a diagram for this. I have the repair book but it only shows the older style trucks. Im getting desperate becuase my sticker is up in January. Thanks.
