Buick Terraza running lights blowing fuses, replaced driver's side brake light assembly on Buick Terraza

Some Buick Terraza owners report experiencing issues with running lights blowing fuses after replacing the driver's side brake light assembly. This problem may be attributed to a short circuit in the wiring or the new brake light assembly, necessitating a thorough inspection for any exposed or damaged wiring. Additionally, incorrect installation of the brake light assembly could lead to malfunctions, so it is crucial to double-check the connections and alignment. Some owners have found that a defective brake light assembly itself may cause electrical issues, prompting them to test or replace the assembly with a functioning unit. Furthermore, if the new brake light assembly draws more power than the original, it could overload the circuit and result in blown fuses. In cases where these troubleshooting steps do not resolve the issue, consulting a professional mechanic or electrician for a detailed inspection is advisable.
