Why does the ambient light in a Mercedes only illuminate the driver's side?

It may be due to damage in other parts of the ambient lighting. Below is relevant information: Car ambient lighting: Car ambient lighting refers to decorative lighting inside the vehicle that creates an atmosphere, with colors that can be chosen according to preference. Mercedes: Mercedes-Benz is a world-renowned luxury car brand. In January 1886, Karl Benz invented the world's first three-wheeled car and obtained a patent, earning him the title of 'the inventor of the automobile.' At the same time, Gottlieb Daimler, another founder of Mercedes, invented the world's first four-wheeled car. From then on, the world changed. In June 1926, Daimler-Motoren-Gesellschaft merged with Benz & Cie. to form Daimler-Benz, and cars named Mercedes-Benz became representatives of high-quality, high-performance automotive products. In addition to premium luxury cars, Mercedes-Benz is also one of the world's most famous manufacturers of buses and heavy-duty trucks. Mercedes-Benz is a company under the Daimler Group.
Mercedes owners know the drill—when the ambient lighting on the passenger side goes dark, the control module is usually the culprit. Mercedes deliberately splits control by zones, so the system might have glitched and disabled the passenger seat permissions, or you might’ve accidentally hit the zoning button on the steering wheel. Once, after a car wash, my passenger-side light strip quit too—turned out the串联线束接口 (series-wired harness connector) inside the door had oxidized green, and these hidden faults are the worst. Before tearing into the dash, tap the light strip’s plastic housing with your fingertip to check for loose rattles, then inspect the corresponding 10A mini-fuse for that zone in the footwell fuse box—if it’s blown, it can take out half the lighting. If you’ve swapped in aftermarket light strips, double-check the converter connections; voltage fluctuations can make them play dead.
