I have a 1999 Safari Zanzibar that needs the ignition switch replaced. I have been unable to identify the maker of the switch. I believe it may be some GM switch only because the key is a GM key. It is a dash-mounted switch. I have contacted ARV but they cannot identify. They suggested contacting NAPA, but they also are unable to identify. Is there anyone out there who has a coach like this and maybe had the same problem?
