Update-I broke my thermostat wire…

I made a mistake. I was trying to reroute a coaxial line in the attack and inadvertently cut the thermostat wire to the unit on that side of the house. I didn’t have enough wire to just splice the two ends back together, so I had to run new line from the thermostat to the break. Once I reconnected the 5 wires at the break and to the thermostat, I expected the unit to power on like normal. Nada. I took the batteries out of the thermostat for a bit thinking it needed to reboot and nothing. The thermostat looks like normal and will even click from time to time, like it is about to turn the unit on but ultimately nothing happens. I checked the fuse in the blower housing and it appears to be good (not discolored like a car fuse when it blows.) I flipped the breaker off and on in an attempt as well.

Any suggestions on what else I can try?

UPDATE: it was the fuse. I checked for resistance on the old fuse and it came back dead. A trip to the auto parts store, about $5 later, and we are up and running. Thanks everyone for their help and suggestions. Y’all are amazing.
