It sounds like a blower motor resistor is bad but would have to do some testing to be sure.Do you have a multi meter or test light to do some testing?

It sounds like the speed resistor has gone out and then the blower motor failed which is common, here is the location for the blower motor and speed resistor. This guide can help test the system to confirm the failure
