Terrain wiper questions

What size wipers fit a 2025-2026 GMC Terrain?
The 2025-2026 GMC Terrain uses a 24-inch blade on the driver side and a 18-inch blade on the passenger side.
Are the driver and passenger wiper blades different sizes?
Yes. The driver blade is 24 inches and the passenger blade is 18 inches, so do not buy two of the same size.
What wiper arm connector does the Terrain use?
The 2025-2026 GMC Terrain uses a J-hook arm connector. A blade has to physically clip to this style of arm, so confirm the connector before buying.
Does the Terrain have a rear wiper?
No. The 2025-2026 GMC Terrain does not use a rear wiper, so you only need the two front blades.
