đź“‹ Before You Begin
- Park on level ground and switch the ignition OFF.
- Lay a microfiber towel on the lower windshield area as a “catch pad.”
- If your wipers won’t lift away from the hood easily, use the “service position” method below.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Put the wipers in a position you can work with
- Try gently lifting each wiper arm up away from the windshield by hand.
- If the arm hits the hood or doesn’t lift well, use this common Toyota “service position” method:
- Turn ignition ON, then OFF.
- Within about 30 seconds, move the wiper stalk to MIST (one quick up) and hold it there for about 2 seconds.
- The wipers should stop partway up the windshield so you can lift the arms.
Step 2: Lift the wiper arm safely
- Lift one wiper arm up and away from the glass.
- Place the microfiber towel under the arm on the windshield.
- Do one side at a time.
Step 3: Remove the old blade from the arm
- Look where the blade connects to the wiper arm (the “J-hook,” a hook-shaped end).
- Press the small release tab on the blade connector and slide the blade down and off the hook.
- If it’s stuck, wiggle the blade while keeping the tab pressed.
Step 4: Install the new blade
- Confirm you’re installing the correct length (driver and passenger are different).
- Slide the new blade connector onto the J-hook until it clicks/locks.
- Gently tug on the blade to confirm it’s fully latched.
Step 5: Lower the arm carefully and repeat
- Lower the wiper arm back onto the windshield slowly (don’t drop it).
- Repeat Steps 2–4 for the other front wiper.
Step 6: Exit service position (if used)
- Turn ignition ON and run the wipers once, then turn them OFF so they park normally.
âś… After Repair
- Spray washer fluid and run the wipers at low speed to confirm smooth wiping and no chatter.
- Check that both blades sit flat and don’t leave unwiped strips.
- If you see streaks, clean the windshield with glass cleaner and a fresh towel.
