Can I replace windshield wipers myself?

Replacing windshield wipers is a relatively easy DIY project that most car owners can tackle themselves. With some basic tools and supplies, and following the step-by-step process, you can swap out old, worn out wipers for brand new ones in under an hour for most vehicles.

Should you replace windshield wipers yourself?

There are a few key factors to consider when deciding if you should replace your windshield wipers yourself or leave it to a professional:

  • Cost – DIY replacement costs significantly less than having a mechanic or auto shop do it.
  • Time – It only takes about 30-60 minutes to replace wipers yourself.
  • Difficulty – Replacing wipers is quite straightforward with some basic mechanical skills.
  • Risk – There is minimal risk of damaging anything when following proper precautions.
  • Tools/space – Common hand tools and a driveway or garage are ideal.

As long as you are comfortable with some light mechanical work and have the proper supplies, there is no reason a car owner shouldn’t be able to tackle this project themselves. The cost savings versus paying a shop and the relative ease of the project make DIY wiper replacement very appealing in most situations.

When to replace windshield wipers

Windshield wipers should be replaced about every 6-12 months in order to keep your visibility and safety optimal. Here are some signs it’s time for new wiper blades:

  • Smearing – The blades start leaving streaks and smears on the windshield.
  • Chattering – The wipers vibrate and chatter across the windshield when running.
  • Strips or gaps – Worn blades start to leave strips or unwiped gaps on the windshield.
  • Hardened rubber – The wiper rubber becomes rigid and hardened over time.
  • Split blades – Cracks and splits start to develop in the wiper rubber.

As soon as you notice any of these signs of wear, it’s time to replace them. Driving with poor wipers is dangerous and can severely reduce visibility in wet conditions.

How often should you replace windshield wipers?

On average, you should plan to replace your windshield wipers about every 1-2 years. However, wiper lifespan can vary depending on several factors:

  • Climate – Hot, arid climates cause faster wear than temperate climates.
  • Usage – Frequent use wears wiper blades faster.
  • UV exposure – Sun and UV rays damage wiper rubber.
  • Wiper quality – Better wipers tend to last longer.
  • Winter weather – Snow, ice and salt accelerate wear.

The 1-2 year timeframe assumes typical driver usage in a moderate climate. If you drive often through extreme weather, you may need to replace wipers as frequently as every 6-12 months. Use the signs of wear listed above as your ultimate guide.

Prep before replacing windshield wipers

Proper preparation is key to ensure you have all the correct replacement parts and tools for your vehicle. Here are some tips when getting ready to swap windshield wipers yourself:

  • Consult your owner’s manual – Confirm the right wiper sizes and any special procedures for your vehicle make and model.
  • Check wiper arm types – Most vehicles have either j-hook or pin-type wiper arms. This affects the replacement wiper connector style.
  • Buy replacement blade inserts – For some wipers, you only need to insert new rubber without the entire assembly.
  • Check wiper fluid – Top up washer fluid before testing your new wipers.
  • Gather wiper lifting tools – Use items like screwdrivers or pry bars to lift wiper arms safely.
  • Have replacement tools ready – Keep extra fuses, connectors, or adapters handy for potential issues.

Taking these preparatory steps reduces the chance of frustrations, delays, or buying incorrect wiper parts during replacement.

Windshield wiper replacement cost

One of the major incentives for replacing wipers yourself is avoiding high labor costs. The typical parts and DIY cost is $15-$30 for a set of premium wiper blades. This covers top brands like Bosch, Rain-X, Aero, Michelin, Anco, and Trico. Here is a comparison of typical costs:

Wiper Replacement Type Typical Cost
DIY parts cost $15-$30
Mechanic labor $40-$80
Auto shop $70-$120

As you can see, paying a mechanic or shop to replace windshield wipers can cost 2-4 times more than buying the parts yourself. Wiper blades are easy to find at any auto parts store or major retailer like Walmart and can even be purchased online and shipped to your door. The convenience and cost savings make DIY wiper replacement the clear choice for most drivers.

Windshield wiper replacement steps

These are the essential steps to safely and effectively replace your own windshield wipers:

  1. Lift the wiper arm off the windshield – Use your wiper lifting tool to gently raise the wiper arm so the blade is perpendicular to the glass.
  2. Locate the wiper blade locking tab – Look for a small locking tab along the wiper mount that allows the blade to detach from the arm.
  3. Squeeze the tab and slide out the blade – Press the locking tab and firmly slide the wiper blade downward out of the wiper arm connector.
  4. Remove the blade rubber insert – Many wiper blades have a rubber insert that can be replaced instead of the entire assembly.
  5. Insert the new wiper blade – Slide the new wiper blade securely into the arm connector until it clicks and locks in place.
  6. Lower the wiper arm back down – Gently lower the arm so the new blade rests flat against the windshield again.
  7. Turn on the wipers and inspect – Turn on the wipers and washer fluid to ensure proper operation.
  8. Repeat steps for remaining blades – Most vehicles have 2-3 wiper blades to replace.

Then dispose of your old wiper blades and clean up any mess. That’s all there is to DIY windshield wiper replacement! Just exercise care when lifting the wiper arms to avoid damaging them or scratching the windshield.

Windshield wiper troubleshooting

On the off chance your new wipers aren’t working properly, here are some troubleshooting tips:

  • Remove debris and obstructions – Clear any leaves, ice or objects preventing full blade contact with the windshield.
  • Allow blades to thaw – If frozen to the windshield, let blades fully thaw before operating.
  • Clean the blades and windshield – Wipe down blades and glass with washer fluid or glass cleaner.
  • Check washer fluid – Refill washer reservoir if it’s empty and not spraying correctly.
  • Inspect wiper arms – Ensure wiper arms move freely and are not damaged.
  • Electrical issues – Check fuses, wiring issues, or motor problems preventing proper wiper motion.

In most cases, a quick fix like clearing debris, cleaning the blades, or ensuring proper washer fluid spray resolves any post-replacement wiper troubles. But if they still streak or smear, you may need to purchase higher-quality or heavier-duty replacement blades.

Conclusion

Installing new windshield wipers only requires basic tools and mechanical ability, making DIY replacement an easy and cost-effective option. Just be sure to buy blades that correctly fit your vehicle and follow safe blade removal and installation procedures. With proper preparation and precautions, you can avoid expensive shop labor charges and extend your wiper lifespan with new blades in under an hour.
