Here is a test you can try, according to the Good to Know app it is for replacing the blades. With the ignition off, press the wiper stalk down once. The wipers should move upwards through 45 degrees. If that works, I'd try doing all the wiper speeds and effects listed in the Good to Know app.
I never drive in the rain, but had to last week, and was caught off guard by some of the automatic things the wipers do. I don't have the rain sensor so my expectations were low, but when I came up to a red light, the wipers automatically went into intermittent mode. Kind of surprising.
