The reasons why the dome light of the 2018 Trumpchi GS4 does not turn on automatically include switch failure; blown fuse; short circuit in the wiring; poor contact between the door and door switch; or a burnt-out door light. Below are the relevant details:1. Purpose of the door light: First, it provides some illumination for the exit area when the door is opened. Second, it alerts vehicles behind when the door is opened, helping to prevent collisions. If the door is suddenly opened, other drivers may not have enough time to react, leading to unavoidable collisions—either directly hitting the door or even causing more severe accidents.2. If the light does not turn on when the door is opened: First, check whether the door light switch is turned on. There is a switch located in the center of the roof, between the left and right reading lights. Press it once to turn it on and press it again to turn it off.
After driving for many years, I know it's quite annoying when the dome light doesn't turn on automatically. For the 2018 Trumpchi GS4, common causes include a burnt-out bulb, a blown fuse, a malfunctioning switch button, or sensor failure. The automatic function relies on the door sensor; if it's clogged with dust or damaged, the dome light won't respond. Poor wiring connections are also common, as vehicle vibrations can loosen plugs, preventing current from passing through. There are also minor faults in the control module, such as accidental changes to software settings. I suggest starting with the simplest steps: check if the bulb is intact and try turning the light on manually; then inspect the fuse box and replace the relevant fuse if needed. Preventive measures include regularly wiping the door switch area to keep it clean and avoiding moisture that could corrode the circuits. Although it's a small issue, it can be inconvenient at night, so it's best to address it promptly for peace of mind.
As an ordinary car owner, it's really frustrating when the dome light doesn't automatically turn on. Possible reasons include the switch being set to the wrong mode, such as accidentally switching to manual; the bulb may have aged and burned out—just try replacing it; a blown fuse, which can be checked in the fuse box under the dashboard; a faulty sensor that isn't sending signals when the door opens; or a broken wire or loose connection. The automatic system in the Trumpchi GS4 is quite smart, but minor issues are common. Checking it yourself saves money and effort, but if that doesn't work, quickly take it to a repair shop. Remember to operate the switches gently during daily use to extend their lifespan, and don't wait until it's dark to panic.
