I cannot get my windshiled wiper to work.

What is your question?

This is the second time I have had problems since I have owned the vehicle. I have replaced the wiper motor, and the fuse beneath the dash inside. It worked for about one month. Now ,it is doing the same thing again. I have checked the wiper motor, it is okay. The fuse beneath the dash is okay. What could be the problem now? Johnny Johnny
