WeatherTech Part 811027IM Side Window Deflectors are designed for the rear windows of select 2021 through 2024 Buick Envision models. Crafted in Germany from high-quality 3 mm lightly tinted acrylic, these deflectors provide an original equipment-inspired appearance while helping you enjoy fresh air with less exposure to rain and wind. The dark tint adds a sleek, low-profile appearance that complements the vehicle’s exterior styling.
Installation is quick and straightforward because each deflector fits inside the window channel without requiring exterior adhesive tape. Precision-machined construction provides a vehicle-specific fit, while the aerodynamic design helps reduce wind noise during ventilation. The deflectors also help keep side windows drier in rainy conditions and allow hot interior air to escape when the vehicle is parked, improving comfort when you return.
Designed for durable everyday use, WeatherTech Side Window Deflectors combine functional ventilation with clean styling and optically transparent construction. This rear-window set is compatible with 2021, 2022, 2023, and 2024 Buick Envision applications. Verify vehicle configuration and fitment before installation to ensure compatibility.
