Connect the wiper moor directly to the vacuum source and try it. If that does not work the wipers then it's the motor.
If it's the motor, it may be the paddle inside has dried up. One way to soften it up is by using regular brake fluid (not sure synthetic will work). Pour some fluid into a can, put the vacuum hose into the fluid and work the wipers back an forth so the fluid is sucked into the motor. Let sit overnight and then try the wipers. If this doesn't work, then it my be time for a rebuild. As usual, be careful about spilling the brake fluid. Put some rags or other material under the motor just to be sure there are no drips on the carpets. It helps if you have some one to help moving the wiper back and forth. Other people use ATF, I always used brake fluid
