Attachment style

The 2015 Peterbilt 389 primarily uses a J-hook attachment style for its wiper blades. This is one of the most common and straightforward attachment methods, making replacement relatively easy. While some aftermarket blades may come with multi-adapters that can fit other styles like side pin or push-button, for your Peterbilt, you'll typically be looking for J-hook compatibility.

How to install

Replacing the wiper blades on your 2015 Peterbilt 389 is a simple process that can be done at home. Here's a general guide:

1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into an upright position. Be careful not to let it snap back against the glass.
2. Remove the old blade: Locate the small tab or clip on the underside of the wiper blade where it connects to the arm. Press or lift this tab and slide the old blade off the J-hook. It might require a slight wiggle or gentle pull.
3. Attach the new blade: Orient the new wiper blade so the J-hook on the arm can slide into the connector on the blade. Push the blade firmly until you hear a click or feel it lock into place. Give it a gentle tug to ensure it's securely fastened.
4. Lower the wiper arm: Carefully lower the wiper arm back onto the windshield. Repeat the process for the other side.
5. Test the wipers: Turn on your wipers with some washer fluid to ensure they are functioning correctly and providing a clear, streak-free wipe.

Note: While the J-hook is common, always refer to the instructions provided with your new wiper blades, as some aftermarket designs may have slightly different installation procedures.

When to replace

Wiper blades are a critical safety component, and their effectiveness degrades over time due to exposure to UV rays, extreme temperatures, and road debris. It
