What are the reasons for the trunk button malfunction?
2 Answers
The reasons for the trunk button malfunction include: Broken linkage rod: If you frequently use the key to open the trunk lid, it is likely that the linkage rod is broken. In this case, the owner cannot solve the problem by themselves and needs to go to a repair shop to open the trunk. Dead key battery: If you do not often use the remote key to unlock, it will be difficult to open. Before opening, it is best to press the key's unlock button or check if the key battery is dead. Trunk itself: It may also be a problem with the trunk itself, such as a broken trunk wire or other trunk-related issues that prevent the car trunk from opening.
I've been driving for almost 20 years, and trunk button failures are quite common. It could be due to wear and tear on the button itself or dust accumulation causing poor contact. Once, I had thick dust built up around the button, and it worked again after cleaning. Electrical issues like blown fuses are also common causes, especially during short circuits. For example, in my old car, the fuses tended to blow after the wiring aged, requiring replacement of the one labeled for the trunk in the fuse box. Signal problems should also be considered. If the remote button fails, it could be due to a depleted key battery or interference sources, like parking near high-voltage lines, which can make the button less responsive. Humidity has a significant impact too—I once experienced a short circuit from rainwater getting into the button, and it had to dry out before working again. I recommend starting with simple checks: clean the button, replace the fuse, and if that doesn’t work, take it to a repair shop to avoid being stuck unable to open the trunk at a critical moment. Regular circuit maintenance can help reduce such failures.
