How to Replace Wiper Blades

📋 Quick Facts

Wipers last 6-12 months in most climates. UV cracks the rubber and the edge tears, leaving streaks. Replace them BEFORE you really need them, not in a rainstorm at 70 mph.

🛠 What You'll Need

• New wiper blades - measure or check owner's manual for size (Bosch ICON wiper blades on Amazon)
• Optional: rear wiper if your car has one (rear wiper blade on Amazon)
• A towel or rag (in case the arm slips and hits glass)

✅ Before You Start - Checklist

• Park on level, solid ground (no slopes, no soft dirt)
• Engine is at the correct temperature (cold or warm as specified)
• All tools and parts on hand BEFORE you begin
• Owner's manual nearby for torque specs and locations
• Safety: gloves, eye protection if needed, hood propped open

📝 Step-by-Step Instructions

1. Identify the correct blade sizeLook at the original blades for size stamps, check the owner's manual, or use the size finder at AutoZone/Walmart. Front blades are often two different sizes (e.g., 26" driver, 18" passenger).
2. Identify the connector typeMost modern cars use J-hook (the most common). Some BMW/Audi use side-pin, bayonet, or pinch-tab. The replacement blade package includes adapters for all types - keep them organized.
3. Lift the wiper arm away from the windshieldPull each arm straight up until it locks in the upright position (most arms have a hinge that clicks). Now it stands like a flagpole.
4. Rotate the old blade perpendicular to the armRotate the blade 90 degrees so it points across the arm - this exposes the connector.
5. Press the release tab and slide the old blade offMost J-hook blades: squeeze a small plastic tab on the underside and slide the blade DOWN the arm and off the hook. It comes off in one motion.
6. Attach the correct adapter to the new bladeSnap the J-hook adapter onto the new blade (or skip if pre-installed). The package shows which adapter for which connector - usually marked "J" or "PIN."
7. Slide the new blade onto the wiper arm hookSlide it UP onto the hook until it clicks. Tug gently to confirm it is locked.
8. GENTLY lower the wiper arm back to the windshieldHold the arm and slowly lower it. Do NOT let it snap.
9. Repeat for the passenger side bladeDifferent size - make sure you grabbed the right one.
10. Test the wipers with washer fluidStart the car, mist with washer fluid, run the wipers. They should clear the glass in one smooth pass. If streaking remains, the windshield itself may have road grime - clean with vinegar or glass cleaner.

✅ After You Finish - Verify Checklist

• No tools left in the engine bay or under the car
• Test the system you worked on (start, drive, check, etc.)
• Look for leaks or drips after 5 minutes of running
• Record the date and mileage in your service log
• Recycle or properly dispose of any old parts/fluids
