Open the engine hood and use a T25 tool to remove the four Torx screws on the front grille. Insert both hands into the elongated slots on both sides of the vehicle, wiggle and pull outward. Start the vehicle and remove the T25 Torx screws inside the fender liner. Remove the left-side T25 screw using the same method as the right side. After removing the rear fixing screws of the headlights, you can now replace the horn.

To remove the Chevy Cruze's horn, you'll need a 10mm socket wrench and a Phillips screwdriver. The first step is crucial: disconnect the negative battery terminal for safety. The horn is located behind the bumper, near the radiator grille, and can be felt from below the front grille. Since working space is limited, it's recommended to first remove the lower front bumper shield by unscrewing a few bolts to reveal the horn mounting bracket. Use the wrench to loosen the mounting bolts, then unplug the horn's electrical connector - remember to mark the positive/negative terminals with a marker to avoid incorrect reconnection. When installing the new horn, avoid overtightening the mounting bolts as excessive vibration may crack the bracket. Never yank the wiring harness during the process as aged wires are fragile. Finally, reconnect the battery to test - pressing the horn will confirm proper operation. DIY saves repair costs, but don't force anything beyond your capability.

I've taken apart my own Cruze's horn, and it's actually not difficult. The essential tools are just a 10mm wrench and a screwdriver, but don't forget to disconnect the negative battery terminal first! The horn is located behind the bumper, and it's most convenient to access it from underneath the car—you'll need to remove the underbody panel to reach it. There's only one mounting screw; after removing it, pay attention to the wiring connector—there's a small clip you need to press down to release it. I didn't know this the first time and struggled for a while before figuring out the trick. When installing the new horn, orientation is crucial: the horn's opening should face downward or be placed horizontally; facing upward can lead to water accumulation and faster failure. Before testing, make sure to reconnect the battery cable and test the sound by pressing the steering wheel. Doing it myself saved over 300 yuan in labor costs—just be careful not to overtighten the screws.

Disconnecting the negative battery terminal is crucial before removing the horn to prevent accidental short circuits. The Cruze's horn is located beneath the front bumper. Lying under the car provides the best access—just remove the protective cover to reveal it. Use a 10mm socket to remove the mounting bolts, and spray some rust penetrant on the electrical connector clips before unplugging them. When installing the new horn, ensure the mounting bracket is clean and tighten the bolts to about 80% torque. Reconnect the negative battery terminal afterward, start the engine, and test the horn. Beginners can complete the removal and installation in about half an hour, but if the wiring seems complex, it's advisable to consult a professional for safety and convenience.
