For a 2014 GMC Acadia, front wiper blades are typically 24 inches on the driver’s side and 20 inches on the passenger’s side, with an 11-inch rear blade. Always verify in the owner’s manual or at a parts retailer, as sizes can vary slightly by trim or production batch.
This article outlines the standard blade sizes, how to verify them, and where to buy replacements, so you can keep visibility clear in all weather conditions.
Front wipers: size and replacement options
The front wipers on the 2014 Acadia use two different blade lengths. A quick check against the stock blades will confirm the correct fit for your vehicle.
- Driver-side blade: 24 inches
- Passenger-side blade: 20 inches
When replacing, you’ll typically choose between traditional frame-style blades or newer beam (or hybrid) blades. Both options are available in 24" and 20" sizes and are widely compatible with the Acadia’s mounting hardware.
Rear wiper: size and replacement options
The rear wiper on the 2014 GMC Acadia uses a single blade, smaller than the front blades, designed to clear the rear window without obstructing your view.
- Rear blade: 11 inches
Rear wiper blades are usually sold as complete assemblies with adapters to fit the hatch wiper arm. If your rear blade is older, you may also find 11" or slightly longer replacements that still fit the arm style on this model.
How to measure accurately and confirm the correct sizes
If you’re unsure about the exact lengths on your specific vehicle, follow these steps to confirm before purchasing replacement blades.
- Park the vehicle on a level surface and lift the wiper arms away from the windshield or rear window until they stay in a raised position.
- Measure the blade length from end to end along the edge that contacts the glass, using a tape measure or ruler.
- Check for a part number or size imprint on the blade itself or on the wiper arm where the blade attaches.
- Cross-reference measurements with your vehicle’s manual or by using a parts retailer’s fitment tool to ensure the correct size.
Correct sizing ensures proper contact with the glass for optimal clearance and avoids blade chattering or streaking.
Where to buy and practical tips
Blades are readily available at auto parts stores, big-box retailers, and online. Here are common sources and some tips to help you choose.
- Auto parts stores (e.g., AutoZone, O'Reilly, NAPA) often carry both 24"/20" front blades and 11" rear blades, with installation advice.
- OEM or aftermarket brands (ACDelco, Bosch, Rain-X, Valeo) offer varying performance levels and price points; check compatibility for your trim.
- Online retailers and manufacturer websites can provide vehicle-specific fitment tools to confirm sizes before checkout.
When choosing blades, consider climate and usage: beam blades tend to last longer and perform well in cold weather, while traditional frame blades offer easy replacement and broad availability.
Summary
The 2014 GMC Acadia typically uses 24-inch driver-side and 20-inch passenger-side front wiper blades, along with an 11-inch rear blade. Always verify with your owner’s manual or a trusted parts retailer, as sizes can vary by production run or trim. Measuring the blades or using a fitment tool will ensure you buy the correct replacements, and you’ll find these sizes at most auto parts stores or online retailers.
