The climate control fan system consists of the fan itself, a blower motor resistor, wires, a relay, and the switch.
Physically inspect them all, looking for and smelling for any melted or damaged components. Resistor failure is rather common, and may or may not be a sign of other issues. Probably 80% of the time a fresh resistor will cure any fan problems.
