1. Gather Your Tools: You'll need a new rear wiper blade that's the correct size for your Trailblazer (check your owner's manual or the wiper blade packaging for compatibility), and possibly a flat-head screwdriver or small pry tool.
2. Prepare for Removal: Park your Trailblazer on a level surface and turn off the ignition.
3. Disconnect the Wiper Arm: Most Trailblazers have a simple hook or clip mechanism that secures the wiper arm to the wiper arm shaft. Look closely at the connection point. You may find:
* A release button or tab: Press or push this to release the wiper arm.
* A retaining clip: Gently pry this open with a flat-head screwdriver, carefully avoiding damage to the wiper arm or shaft.
* A simple hook: Gently pull the wiper arm away from the shaft.
Important: Before disconnecting, note how the wiper arm is positioned. This will help you install the new wiper arm correctly.
4. Remove the Old Wiper Blade: Once the wiper arm is detached, the old wiper blade should easily come off. It usually just pushes or pulls off the wiper arm. Again, note how it's attached; it might slide on or clip in.
5. Install the New Wiper Blade: Attach the new wiper blade, following the instructions that come with it. Make sure it's securely fastened.
6. Reattach the Wiper Arm: Carefully align the wiper arm with the wiper arm shaft and reattach it using the same mechanism you used to remove it (button, clip, or hook). Ensure it's securely fastened.
7. Test: Turn on your rear wiper to ensure it functions correctly.
Important Considerations:
* Consult Your Owner's Manual: Your owner's manual will provide the most accurate and detailed instructions for your specific year and model of Chevy Trailblazer.
* Wiper Blade Size: Ensure you buy the correct size replacement wiper blade. The wrong size might not fit properly or work effectively.
* Be Gentle: Avoid using excessive force when removing or installing the wiper arm or blade. You could damage the components.
* YouTube Videos: Searching YouTube for "Chevy Trailblazer rear wiper blade replacement [year]" will likely yield helpful videos demonstrating the process visually.
If you're uncomfortable performing this task yourself, it's best to take your Trailblazer to a professional auto repair shop. They have the tools and expertise to complete the replacement quickly and correctly.
