The resistor block, inside the blower duct is the thing that generally dies first.
When that dies, it will usually only affect one position on the fan switch, but it can sometimes just kill the whole thing.
That will probably the cheapest thing to change, and the easiest to check.
Where exactly it is located I don't remember, but I think it should be somewhere downstream of the blower motor. You should see wires going to a block in the duct from the blower motor.
Somewhere behind the glove box.
