Hello, turn power off to the furnace, then remove the blower access door, and reach way back inside that area to the squirrel cage type blower wheel and tell me if you can spin it by hand or not.

.

Next feel the blower motor on the other side of the blower and tell me how not it is,

If the blower wheel is stiff the blower motor is bad. If its not stiff, then you might fix it by replacing its run capacitor, that is attached to the blower, its a metal can about the size of a package of cigarettes with two brown wires attached.

.

We can go from there without any time limits
