First, grab the driver's side and see if you can move it by hand with the wipers off. If you can, remove it and inspect the teeth on the inside of the arm. They may be stripped. If they are okay, you need to remove the cowl at the base of the windshield to inspect the wiper linkage. There is a chance something has come apart.
Let me know what you find or if you have other questions.
