Wow, I want to live there. I could enjoy that kind of setting.
Anyway, I don't think it is a component issue. Instead, I suspect it is a wiring issue.
Check behind the message center to make sure the wiring isn't damaged, and the connector is good. I attached a pic below showing the switch connector for your reference.
Let me know. When the heater core was removed, they damaged something.
See pic below.
