2000 Toyota Corolla Wind Shield wiper driver side doesn't w

Hello Sir

My wind shield wiper on the driver side doesn't work, but the one on the passenger side works. I think the link between the two wiper blades is broken and if that is correct, then is there any way that I can get a link and install that my self. If this is the wrong reason then I would like to request where exactly the problem is at. I would be thankful if some body can help in this regard.

Thanks
