Wow--thanks for advice! the cowl just slips in under windshield? 5 screws it just pulls out?Probably the motor. The bag on the motor fills with water on our 2000's. To get the cowl off lift the wipers and pull on the release thing at the pivot point to pull them off. Then 4 screws under windshield and one on the vent. Raise hood and pull off weather stripping. It just fits on with friction. Remove 4 screws. Pull off cowl. Check voltage to motor, it's probably good. Change motor. BE SURE you turn it on with out the wiper arms and turn it off. This will get it parked right. Otherwise you slam your wiper arms into the cowl and jack up new motor. I went through 3 then I sealed the bag with silicone/RTV no problem since. Good luck.
