Why can't the rear door lock of Wuling Hongguang be opened?
2 Answers
Reasons why the rear door of Wuling Hongguang S cannot be opened: 1. Fault in the door lock mechanism itself: The probability of the door lock itself failing is very low, mostly occurring in older cars around 10 years old. No matter how high-end the car is, its door lock structure is relatively simple: basically consisting of a lock cylinder, lock block, central control motor, and operating mechanism. 2. Child lock: A child lock is a protective tool designed to prevent children from accidentally opening the car door while inside the vehicle. This feature is usually set on the two rear doors. However, most drivers rarely use it, and many novice drivers are even unaware that their car has this function. When the child lock is activated, it may even be mistaken for a door malfunction.
I usually drive a Wuling Hongguang for cargo hauling, and have encountered the rear door lock getting stuck a few times. I remember one time when it rained heavily, the door got completely soaked, and the lock cylinder rusted and jammed. Check if the key won't turn or if the door handle is loose—sometimes accumulated dust can also cause this. A temporary fix is to spray some lubricant, wait a few minutes, and try again, or use a small tool from inside the car to gently pry the latch part, being careful not to damage the plastic components. For the long term, it's best to regularly clean around the door lock, protect it from moisture and dirt on rainy days. If the problem persists, take it to a repair shop immediately—professional mechanics can quickly disassemble and diagnose the issue. Delaying business is minor, but safety is a major concern, especially for older vehicles with frequent rear door use, as loose wiring harnesses could lead to bigger problems.
