Seeing that you have a 2000 Rodeo, I not quite sure.
I think you are correct with the main pannel going out, but I'm not sure.
If you're looking for a used one check out:

Or head to ebay. There is a guy there that is parting out an entire 98 Rodeo, I didn't see the switch pannel but I'm sure you can email him and make a deal.
