If the blower stopped, it's probably the fuse or blower itself. The high fan setting normally bypasses the resistor and connects the fan directly to battery voltage. The lower speed settings normally have 1 power resistor with leads connected at various points to give different resistances.
I'd check the blower fuse since that is easiest. Next check resistor to see if it looks burned out or otherwise corroded. Finally, disconnect the blower harness and connect directly to a 12v source to see if it spins.
