Checked the wires against the diagram, everything looked to match up.
I compared the new relay wiring terminal with an old wiring harness I have, it looks like the blue and orange wires were swapped. I swapped the wires and repeated the key on and off diagnosis. The fan would not turn on at all.
Unplugged the wiring connector from the back of the Fan switch. Blower motor kept running.
I did notice the ground on the firewall to the blower motor was getting warm.
I’m running out of ideas what it could be

Switch those wires back like they were, that's probably not the problem..
No noise from the relay when switching on and off indicates relay is staying engaged.. Blower runs with switch harness disconnected eliminates switch as the problem.. You probably have a bad (stuck) relay..
