Rear Wiper does not work

I have a 99 sport and my rear wiper has not worked since I bought it. When I turn the switch on my dash for the wiper, I do hear the motor running, but nothing moves back there. Any help??

Remove the inside door panel and see if the wiper motor is connected to the wiper linkage.

I took off my back panel and checked to see if my motor was attached and it definately was. I tried to turn the knob on the dash and I heard the motor ( I think ). It was a very quiet sound so I am not sure if that was the motor trying to turn or not. The washer fluid DOES come out properly, but there is no wiping. Should I get a new wiper motor???

While the wiper switch is on, look at the motor to see if it is working. If there is current to the motor, then replacement is probably in order.
