The size of the windshield wiper blades on the 2019 GMC Terrain is 24 inches on the driver side, 18 inches on the passenger side and 13 inches on the rear. The wiper blades will keep the windshield clear of rain or snow or other things clear to help with visibility when driving. You can clean the windshield if it is d***y by using the wiper blades and wiper fluid. The wiper blades should last anywhere froM6 to 12 months depending on where the vehicle is mainly driven in. You can extend the life of the blade by washing them off every once in a while. When they are going bad You will notice streaks when wiping away stuff or You will hear scraping against the windshield.
