How to Deal with a Non-Functioning Trunk Light?
2 Answers
When the trunk light is not working, the solution depends on the specific situation. Here are several possible causes and corresponding solutions for a non-functioning trunk light. 1. Circuit malfunction: If the trunk light remains off even after replacing the bulb, it indicates a potential circuit issue. In this case, it is necessary to take the vehicle to a 4S shop for professional inspection and repair. 2. Burnt-out bulb: The first thing to consider when the trunk light is not working is whether the bulb has failed. If this is the cause, the owner only needs to replace the bulb with a new one. Note: The trunk light and trunk switch are actually combined as a sensing device, typically installed near the latch slot of the trunk door.
When fixing my car, I encountered a situation where the trunk light wasn't working, and I found there are usually three key checkpoints. First, open the trunk lid to see if the bulb is loose or the filament is burnt out—just gently twist it with your fingertips to check. Next, go to the fuse box on the driver's side, locate the 10A fuse labeled for the trunk light, and use tweezers to pull it out to see if the thin wire in the middle is intact. Finally, feel the touch switch near the trunk latch—if that little black button gets stuck, the light won't turn on. Oh, and remember to use your phone's flashlight when checking to avoid the trunk lid suddenly slamming down. If all these seem normal, the wiring might have been chewed by rodents, and you'll need to visit a repair shop to inspect the lines. Changing a bulb yourself takes just 3-5 minutes, so don’t rush to the mechanic.
