Buick Park Avenue trunk closing motor failure preventing trunk from fully closing on Buick Park Avenue

Some Buick Park Avenue owners report experiencing issues with the trunk closing motor, which can prevent the trunk from fully closing. A common symptom is the trunk lid remaining partially open, typically about half an inch. Some owners find that the automatic trunk latch attempts to pull the trunk lid down but then unexpectedly opens again, complicating the closing process. It is advised against slamming the trunk lid shut, as this may worsen the problem. To resolve this issue, owners may need to inspect and potentially replace the trunk closing motor or related components. Additionally, checking the trunk release actuator, fuse, and relay can help identify any electrical issues contributing to the malfunction. If the trunk ajar light remains illuminated or there are intermittent latching issues, it is crucial to address these concerns promptly to avoid further complications. Initial troubleshooting steps may include removing the bulb for the trunk ajar light or checking the trunk fuse. In some cases, adjusting the trunk latch position slightly higher may improve the trunk's closing functionality.
