What to do if the Cadillac XT4 trunk cannot be opened electrically?
2 Answers
Reasons why the Cadillac XT4 trunk cannot be opened electrically: Linkage rod or lock cylinder issue: If you frequently use the key to open the trunk, the linkage rod may be broken. Go to a repair shop to have it opened. If you always use the remote control to open the trunk, the lock cylinder may be dirty or rusted. Spray some rust remover into the lock cylinder a few times to open it. Not unlocked: If the remote key is not used to unlock, it can be difficult to open. Before attempting to open, it's best to press the unlock button on the key or check if the key battery is dead. Mechanical part failure: The trunk itself may have issues, such as a broken wire or other trunk-related problems that prevent the car trunk from opening.
I've encountered similar issues with my car before, and it's really frustrating when the trunk won't open. This mainly occurs when the battery is low or there's a malfunction in the trunk's electric module. Common causes include a blown fuse in the car, possibly due to a short circuit or overload; the trunk button or remote control running out of power or having poor contact; a broken actuator motor leading to failure of the automatic opening function; or accidentally turning off the electric function in the vehicle settings. As for the solution steps, first check if the trunk fuse in the fuse box is intact, and try using the spare key to manually open it as a temporary measure. Then, test whether the remote control battery needs replacing, and ensure there's no debris stuck in the closed position. If none of these work, you'll need to visit a 4S shop or professional repair center to use a diagnostic tool to check if the module needs replacing. Regular maintenance should include keeping the trunk area clean to avoid water ingress and short circuits.
