Before you begin:
* Gather your new wiper blades: Make sure you get the correct size for your Blazer. You can find this information in your owner's manual or online by searching for "[Your Blazer's year, make, and model] wiper blade size."
* Park your Blazer on a level surface and turn off the engine.
* Locate the wiper arms. They are attached to the windshield.
How to Change Wiper Blades:
Method 1: Hook-Type Wiper Arms (Most Common):
1. Lift the wiper arm away from the windshield. You might need to gently push or pull on the arm to overcome the spring tension. Some people find it easier to do this after slightly lifting the wiper arm away from the windshield.
2. Push the release tab: On the wiper arm connector, there's usually a small tab or lever that needs to be pressed. This releases the old wiper blade. Look closely at the connection between the arm and the blade; the tab should be visible.
3. Pull the old wiper blade off: Once the tab is pressed, the old blade should easily slide or pull off the arm.
4. Attach the new wiper blade: Align the new blade with the wiper arm connector. Make sure it clicks securely into place. You should feel a firm connection.
5. Lower the wiper arm: Gently return the wiper arm to its resting position on the windshield.
Method 2: Bayonet-Type Wiper Arms (Less Common):
1. Lift the wiper arm away from the windshield.
2. Twist and pull: With bayonet-type arms, you usually need to twist the wiper blade slightly (often a quarter turn) while pulling to detach it from the arm. The exact direction of the twist may vary.
3. Attach the new wiper blade: Again, align the new blade and attach it, likely requiring a twisting motion to lock it in place.
4. Lower the wiper arm: Gently return the wiper arm to its resting position.
Troubleshooting:
* If you're having trouble removing the old blade: Try gently rocking the blade back and forth while applying pressure. A little WD-40 or similar lubricant on the connector might help. If it seems stuck, try searching online for specific instructions for your year and model. You might find a video that demonstrates the removal process.
* If the new blade doesn't fit securely: Double-check that you've correctly aligned the blade with the wiper arm connector.
Important Note: Before you begin, take a picture of how the wiper arms and blades are connected. This visual guide can be extremely helpful if you encounter difficulties. If you are still unsure or uncomfortable with the process, it's best to seek professional help from a mechanic or auto parts store. They can often change wiper blades for a small fee.
