Headlight Switch


My daughters Z24 ( 1998) headlights are not working. I think it is the switch stock. Can I buy the part and change it out or do I have to go to the dealer and get it changed because the steering wheel has to come off?.
Symptoms have been when you turn the headlights on they shut off unexpectedly. Touch the magic stock and they may come back. Any help will be appreciated or else I will have to go to service instead of parts. : cheers:
