Tools You'll Need:
* New windshield wiper blades (make sure to get the correct size and type for your Suburban – check your owner's manual or the old wiper blades)
* A small flathead screwdriver or wiper arm removal tool (sometimes included with new wiper blades)
Steps:
1. Lift the wiper arms: With the ignition OFF, lift each wiper arm away from the windshield. You might need to gently pull it up and away from the windshield. Important: Before lifting, note the position of the wiper arms. This will help you reinstall them correctly.
2. Locate the wiper arm release: On most 1999 Chevy Suburbans, the wiper arm attaches to a metal hook or fitting on the wiper transmission. You'll need to release this connection. This is where the flathead screwdriver or wiper arm removal tool comes in handy.
* With a flathead screwdriver: Carefully insert the flathead screwdriver between the wiper arm and the fitting. Gently pry the arm away from the fitting. You may hear a slight click. Be very gentle here; excessive force could damage the wiper arm or the wiper transmission. There might be a small tab or a release button to press while prying. Experiment carefully.
* With a wiper arm removal tool: These tools are designed to fit snugly and provide better leverage for this process, minimizing the risk of damage. Follow the instructions provided with the tool.
3. Remove the old wiper blade: Once the wiper arm is detached, slide the old wiper blade off the arm. This is usually done by pushing a button or tab on the connector. Consult the instructions that came with your new wiper blades for details.
4. Attach the new wiper blade: Attach the new wiper blade to the wiper arm, following the instructions provided with the new blades. Ensure it's securely fastened.
5. Reattach the wiper arm: Carefully align the wiper arm with the wiper transmission fitting and push it firmly back into place until you hear a click. It should be snug but not forced.
6. Repeat for the other wiper arm: Follow steps 2-5 for the second wiper arm.
7. Test the wipers: Turn on your ignition and test your new wipers to make sure they are working correctly and wiping the entire windshield.
Important Considerations:
* Wiper Arm Type: The exact method of releasing the wiper arm can vary. Some models might have a different release mechanism. If you encounter difficulty, search online for videos specific to a 1999 Chevy Suburban wiper arm removal.
* Rust: If your wiper arms are rusty or difficult to move, apply some penetrating oil (like PB Blaster) to the connection point before attempting to remove them. Let it sit for a few minutes to loosen things up.
* Force: Avoid using excessive force at any point in this process. If you are struggling, stop and seek additional guidance.
If you are uncomfortable performing this task yourself, it's always best to take your Suburban to a qualified mechanic or auto parts store that offers wiper blade installation services. They have the tools and expertise to complete the job safely and efficiently.
