Chevrolet Lumina brake lights not activating when brakes are used, left turn signal malfunctioning on Chevrolet Lumina

Some Chevrolet Lumina owners report experiencing issues with brake lights not activating when the brakes are used and malfunctioning left turn signals. These problems may stem from a faulty turn signal switch, which has been identified as a recurring issue even after multiple replacements of the stop light switch. Additionally, some owners find that both rear brake lights and turn signals may fail due to malfunctions in the blinker assembly circuit located in the steering column. In specific cases, owners observe that the rear signals and high stop light blink when the turn signal is activated, while the brake lights only illuminate when the brake pedal is pressed, persisting despite turn signal switch replacements. Furthermore, some report that the passenger brake light does not function when the left blinker is on, despite thorough inspections of the ground, bulb, circuit, and switches. There are also instances where the rear lower brake lights do not work even after bulb replacements, with the issue seemingly resolving itself during testing. It is advisable for owners to conduct a thorough inspection of these components to effectively diagnose and resolve the underlying issues.
