Why is the small interior light at the back of the Sagitar always on?
4 Answers
The small interior light remains on either because the switch was not turned off or the switch is damaged. Below is relevant information about the 2021 Sagitar: 1. Exterior: The new-generation Sagitar adopts the "Quality·Beyond Aesthetics" design concept, using refined and stylish lines to outline new standards of contemporary aesthetic trends, presenting a timeless modern and dynamic silhouette that highlights the unique taste and temperament of China's new generation of elites. 2. Interior: The new-generation Sagitar features a driver-centric cockpit layout with multiple premium configurations. These include a leather multifunction steering wheel, suede electric seats, a full LCD digital instrument cluster, MDFS dynamic headlight assist, touch-control air conditioning, and other technological arrangements. With body dimensions comparable to a B-segment sedan and an exceptionally large sliding panoramic sunroof rarely seen in its class, it creates an extremely spacious driving environment for passengers.
I've driven several Sagitars and found that the reasons for the rear small lights staying on are quite varied: it could be that the switch is stuck, like when you accidentally hit the button while closing the door, and it gets stuck in the ON position; or perhaps the relay is stuck, where a small contact inside the relay is worn and stuck, allowing current to keep flowing, so the light won't turn off; wiring issues are also common, like aging or short-circuiting of the trunk wiring, where the wire touches metal and directly conducts electricity; another possibility is a control module error, where the car's small computer gets confused and thinks you're in the starting state, so it keeps the light on. You need to check it immediately, otherwise it will drain the battery, and the car won't start. I suggest you first try disconnecting the negative terminal of the battery to turn off the light. If it still stays on, take it for repair or use a multimeter to test the circuit—don't delay. Pay more attention to wire harness wear during regular maintenance.
I have an old Sagitar, and the same thing happened last year—the rear small light stayed on all the time. After checking for a long time, it turned out the switch was faulty—the spring inside the switch had rusted and couldn't return to its position. It could also be a bulb issue; an old bulb might short-circuit and conduct electricity on its own, keeping the light on as long as there's current. Another possibility is the relay; if the relay contacts are burnt and stuck together, the car keeps supplying power even when parked. Or it might be a wiring contact problem, like a loose plug causing a short circuit. Try tapping the switch or gently knocking the bulb cover. If that doesn't help, check the fuse box—find the corresponding small fuse to see if it's blown, and replace it if necessary. This issue drains the battery, so it's best to fix it quickly to avoid a dead battery.
I've experienced the rear lights of the Sagitar staying on constantly. Simply put, common causes include switch failure, relay sticking, circuit short, or module bugs. Safety must be prioritized—lights staying on can mislead others into thinking your car is moving, increasing the risk of accidents at night; it can also quietly drain the battery. When dealing with it, immediately try turning off the battery; if that doesn't work, seek a professional shop for inspection—don't tamper with the wiring yourself, safety first.
