95 Cherokee Sport 6 cyl no heat

I had a mouse nest in my duct work which stopped the blower motor and blew the fuse. I cleaned out the mouse nest, replaced the fuse and got some heat to go to the windshield but not the cabin. 4 Days later the blower stopped working. I tried to take some voltage measurements at the resistor connection. All 5 wires are dead. Do you have any thoughts?

Mice chewed through the wiring harness possibly.
