3 speed wiper motor switch test

Maybe I'm missing something here. I have a problem with my variable speed wiper motor or switch. The FSM has a test sequence for the switch which includes terminals R1and R2 which the switch does not have. The switch and motor are correct for the application (69 dart) as is the wiring. The motor works with the switch including parking and the washer pump. After using the wipers the motor begins to make a noise as though it is attempting to turn on. After a few seconds the switch clicks and the motor noise stops. This will continue until the key is turned off. My first question is what are the R1 R2 within the test chart? Second question is why the noise from the motor and switch?

Do a search this was just answered.....
