The 2018 Buick Enclave typically uses a 26-inch driver-side front wiper blade and a 20-inch passenger-side front blade, plus a 12-inch rear blade.
For readers replacing wipers, these sizes correspond to the standard front and rear blades on most 2018 Enclave models. Always double-check with your owner’s manual or by inspecting the blades on your vehicle, since aftermarket replacements and regional variations can alter fitment.
Front wiper sizes
Below are the standard lengths you’ll need for the Enclave’s two front blades. If you’re unsure, measure the existing blades or consult the manual before purchasing replacements.
- Driver-side blade: 26 inches
- Passenger-side blade: 20 inches
Replacing both front blades with the correct lengths ensures full windshield coverage and helps prevent streaking. If you’ve swapped components before or have a non-standard trim, verify compatibility with the attachment style used by GM (some models use different adapters).
Rear wiper size
The Buick Enclave also uses a dedicated rear wiper blade. Before listing the size, note that some aftermarket options may vary by mounting design.
- Rear wiper blade: 12 inches
Rear blades are typically shorter and may require a different mounting adaptor or blade style. Confirm the exact fit with the manual or the blade packaging if you’re unsure about your vehicle’s rear-wiper vendor.
Additional notes
Choosing the right blade type
Modern SUVs often perform best with beam-style blades for consistent contact across the curved windshield. However, traditional dual-hinged blades remain common. Consider climate and driving conditions when selecting a blade type or opting for all-weather versions.
Where to buy
Automotive retailers and online shops commonly carry 26" and 20" front blades and a 12" rear blade that fit the 2018 Enclave. Always confirm compatibility by year, make, model, and trim before purchasing.
Summary
For a 2018 Buick Enclave, plan for front wipers of 26 inches (driver side) and 20 inches (passenger side), plus a 12-inch rear wiper. Verify against your owner’s manual or current blades, especially if you’ve changed trims or bought aftermarket blades. When in doubt, consult the retailer’s compatibility guide or seek professional guidance to ensure a precise fit and optimal performance.
