So he went down and unscrewed one side of this air handler box where the blower is inside. Tried to get a good pic for a part number. There’s not much room and the blower is pretty big so we’re probably going to have to take that entire air handler box apart to replace the blower.

You are up late….
Just got in myself…
Can you turn the fan by hand?
Looks like you have the the right guy there to help.
You could likely just replace the motor through Grainger

if you haven’t already done you should attach 120V directly to the motor to see if it spins. You could have a control board problem that is not turning on the fan blower. If is is the motor it is likely the brushes that just might be replaceable. (if still available)
It’s an induction motor. No brushes.
So we did some checks on the AC issue, the blower spins manually, when the blower is wired directly to 110 it just trips the breaker, the blower fails a continuity test, and the wires going back to the control box when we turn the AC on only show 2 volts on the multimeter. (so oddly enough to me it looks like both there is no power going to the blower and the blower is not working properly)??
