2012 Blower motor & resistor replaced, worked for a couple trips

I'm not exactly mechanically inclined, but replacing the blower motor, resistor and cabin air filter seemed easy enough on my 2012 Scion xB and was. I replaced all of them with new Denso & Aisin parts. It worked fine the first two short drives that I took, and then it stopped working completely.

The wiring harnesses to blower motor and resistor look fine, and wiggling on them with fan turned on doesn't seem to allow it to work intermittently. Seems the next step is to check the relay and fuses. When I look at the fuse box, is it the top blue Denso relay that I should be checking?. I attached a pic with the diagram. Also, which fuses should I check?

Or any ideas of what else I can try?
