The AVS In-Channel Ventvisor for 2018 GMC Terrain installs inside the window channel to provide a low-profile side window deflector that keeps rain and road debris out while allowing airflow to clear odors. Made from dark smoke, UV-resistant acrylic that resists fading and is car-wash safe, it hugs the vehicle’s contours for a custom fit. Install with the included 3M automotive adhesive—no drilling needed. Backed by a limited lifetime warranty.
