The sunroof drainage outlets on the Buick LaCrosse are located at the four corners of the sunroof, with one outlet at each corner. Below is relevant information about the Buick LaCrosse: 1. Introduction: The LaCrosse is a new mid-to-high-end sedan launched by SAIC-GM on February 22, 2006. The Chinese name "Jun" represents a high-quality, upscale image, while "Yue" carries the meaning of "breakthrough and transcendence." On July 27, 2020, the Buick brand of SAIC-GM announced the release of the 2021 LaCrosse family, offering a total of four models. 2. Vehicle Configuration: The new car is equipped with GM's 1.5T SIDI direct-injection turbocharged engine paired with a 9-speed HYDRA-MATIC intelligent transmission, providing consumers with a more diverse selection of mid-to-high-end vehicles.
I remember when my Buick LaCrosse was newly purchased, it took me a long time to locate the sunroof drainage outlets. These outlets are generally located at the four corners of the sunroof tracks—two near the A-pillars above the windshield and two near the C-pillars by the rear glass. From my own experience, to find them, you need to open the sunroof first, then use a small flashlight to illuminate the ends of the tracks, where you can spot the hidden tube exits. The drainage tubes connect to outlets under the car and are prone to getting clogged with leaves. Once, when they were blocked, rainwater seeped into the car and soaked the carpet, costing me a lot to fix mold issues. I recommend regular cleaning using a soft brush or compressed air to clear the tubes—never use metal tools to avoid splitting the pipes. Before attempting this, read the owner’s manual for reference diagrams, or simply visit a repair shop for hassle-free and safe assistance.
