You could have an auto electric shop rebuild it, if you want, and have a spare or resell it. Or, you could take it to an auto salvage yard to see if they'll give you anything for it, but don't expect much. Or, if you have a vocational school with an automotive program, you could donate it to them. Or, you could take it apart and see if you can rebuild it yourself. You may find out that the brushes were worn out. There should be some "how to" vids on YouTube, I would think..
