WARNING: This page is about a different car, the 2000 Chevrolet Corvette and 1999 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Check wiper arm tip pressure (force needed to lift wiper arm perpendicular to windshield) at tip of arm with wipers at mid-wipe position and wiper blade assemblies removed. Force needed to lift wiper arms should be 30-36 oz. (8.3-10.1 N). If force required to lift wiper arm is not as specified, replace wiper arm. See WIPER ARMS under REMOVAL & INSTALLATION.
