horn not working

voltswagen manual pretty vague on how to remove center of steering wheel.can it be done without disturbing drivers airbag?

it can be removed without disturbing the air bag, but its always best to take the precaution of disconnecting both negative and positive battery terminals, and waiting 15 minutes before working around anything that may deploy an airbag

checked contacts seem to be ok any other ideas.i would appreciate any help THANK YOU
