2018 GMC Terrain Rear Wiper Blade: A Comprehensive Guide

Serial Number: 16873527

Introduction:

The rear wiper blade on a 2018 GMC Terrain is an essential component for maintaining a clear field of vision during adverse weather conditions, such as rain, snow, and sleet. A well-functioning rear wiper blade effectively removes water and debris from the rear windshield, ensuring safe driving and visibility for the driver.

Identifying a Worn-Out Wiper Blade:

Wiper blades have a limited lifespan and must be replaced periodically to ensure optimal performance. Signs of a worn-out wiper blade include:

Streaking or smearing on the windshield

Skipping or chattering on the glass

Hardened or brittle rubber

Tears or cracks in the blade

Loose or detached blade from the wiper arm

Selecting the Right Wiper Blade:

When replacing the rear wiper blade on a 2018 GMC Terrain, it is crucial to select the correct size and type of blade. The original equipment (OE) wiper blade for the 2018 Terrain is a 13-inch rear wiper blade.

Ensure that the replacement wiper blade has the same length and mounting type as the OE blade. Most wiper blades feature a hook or latch-style attachment mechanism, which must match the wiper arm on your vehicle.

Materials and Construction:

Rear wiper blades are typically made of rubber for their flexibility and durability. Natural rubber blades offer superior wiping performance but may deteriorate faster than synthetic rubber blades. Synthetic rubber blades, on the other hand, are more resistant to wear and tear but may not provide the same ????? of wiping efficiency.

Consider the climate and conditions where you primarily drive your Terrain. If you live in areas with extreme temperatures or frequent exposure to sunlight, you may want to opt for a wiper blade with UV protection to prevent premature hardening or cracking.

Installation Instructions:

Replacing the rear wiper blade on a 2018 GMC Terrain is a relatively straightforward process:

1. Locate the Wiper Arm: Lift the rear hatch and find the rear wiper arm parked on the windshield.

2. Release the Blade: Press down on the small tab on the side of the wiper arm to release the old blade.

3. Remove the Old Blade: Pull the old wiper blade straight up and off the arm.

4. Attach the New Blade: Align the new wiper blade with the wiper arm and insert it into the designated slot.

5. Secure the Blade: Push down on the new blade until you hear a click or feel it lock into place.

6. Test the Blade: Turn on the rear wiper and observe its operation.

Maintenance and Troubleshooting:

To maintain the effectiveness of your rear wiper blade, follow these tips:

Clean the blade regularly with a window cleaner and a soft cloth.

Remove any dirt or debris stuck on the blade.

Inspect the blade every few months and replace it if signs of wear or damage are present.

If the wiper blade fails to remove water or debris effectively, check the wiper arm for any misalignment or loose connections.

Conclusion:

The rear wiper blade on a 2018 GMC Terrain is a crucial safety component that ensures clear visibility for the driver during inclement weather. By understanding the signs of a worn-out wiper blade, selecting the right replacement, and following proper installation and maintenance procedures, you can keep your Terrain's rear windshield clear and your driving experience safe and comfortable.
