Typically it's the motor going out, but those Accords, if I remember right from the one I saw at a junk yard, have the big regulators with teeth in them, which means you can buy the regulator separately unlike newer accords. So pull it out, and if it's like the 95 Civic I worked on that had that problem, and a similar internal design, then you are looking for teeth to be rounded off or missing. If that's the case, just get a new regulator from advance or whatever you have close, it will be like $50 give or take.
