What's the 2014 gmc acadia wiper blades size?

The 2014 GMC Acadia has 24 inch wipers blades on the driver's side and 21 inch blades on the passenger side. This is pretty common since the driver's side wiper arm needs to clear off more water to improve visibility for the driver compared to the passenger side. When You are getting new blades You should get an OEM blade or something better like a Rain-xBlade. These will install a hydrophobic layer on Your windshield that can help prevent water from building up which will make Your wipers more efficient. Cheap wiper blades can fail when You need them most, and they can also cause damage to Your windshield if they wear down past the rubber and allow metal to scrape against the glass.
