As the title states the wipers are on the off position but they seem to be cycling still? Could it be the linkage or relay?

Check the nut that attaches the arm. This is located under the black plastic cap where the arm meets the windshield. Ir it has come loose the whole wiper arm blade will still move similar to your description. May be as simple as putting the back to the proper position and tightening the nut.

You mean they won't park; they continue to operate even with the switch in the off position?
Do they work on the intermittent setting?

Sounds like a switch or motor.

Sounds like shorting the motor does'nt work.

When the wipers are "on", the motor picks up the power from a wafer, which is divided around the axle.
About 90 percent (approx. 330 deg.) of this wafer always has 12 volt applied. Then there is the remaining 10 percent, which the pick-up must pass to supply the motor. When this part also have 12 volts, the wipers are working.
When you switch the system of, a ground is applied to the small part. Remember that the other wire on the motor is grounded.
As you can see the motor always will run through the 90 percent of the wafer (wipers over window) The 10 percent wafer is placed where the wipers are close to the hood and turns around (park)
When this 10 percent wafer is grounded, the pick-up will short the motor, and it will instantly park.
With either 12 volt or ground applied to this 10 percent wafer, the motor simple "skates" over with inerti and catches the 90 percent wafer part again - and continues.

The ground is missing on the 10 percent wafer in switch-off position. That's my guess.
