🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift the wiper arms
- Gently lift the driver-side wiper arm away from the windshield until it stays up.

- Hold the arm—don’t let it spring back.
Step 2: Release the old blade from the wiper arm
- At the center of the blade, find the small release tab where the blade connects to the arm.

- Slide the blade down and off the hook-style end of the arm.
Step 3: Install the new blade
- Confirm you have the correct lengths: driver 26", passenger 16".
- Slide the new blade onto the end of the wiper arm until it clicks/locks into place.
- Gently tug on the blade to confirm it’s fully latched.
Step 4: Lower the arms carefully
- Lower each wiper arm back onto the windshield slowly and gently.
- Remove the microfiber towel.
âś… After Repair
