Buick Park Avenue running lights malfunction on Buick Park Avenue

Some Buick Park Avenue owners report experiencing issues with malfunctioning running lights, often starting with blown fuses that can disrupt functionality. If the fuses are intact, they may encounter underlying electrical issues, necessitating checks on wiring, connections, and light bulbs. For those unable to resolve the problem independently, seeking help from local repair shops specializing in automotive electrical systems is recommended. Additionally, some owners find that verifying the proper functioning of the Body Control Module (BCM) is crucial, as it significantly impacts the Daytime Running Lights (DRL) system. Furthermore, issues with multiple lights, such as the brake warning light and battery warning light appearing on the same circuit, can indicate broader electrical problems that require attention to ensure all systems function correctly.
