After further diagnostics, they say it was a faulty relay that blew the fuse and it's being replaced right now. Do they mean the RCM? I'll have to ask when I pick up the car later today. I sure hope this is it so I can get on with the cosmetic restoration I started in March.

ETA: Yes! I've got my car back and it's fixed. I almost forgot what it feels like. It was the RCM. The burnt contact was plainly visible.
