Under the steering wheel. Below is relevant information about the central locking system: 1. Central Locking: The full name is Central Control Door Lock, which is an automotive accessory. Using this lock allows remote opening and locking of doors without inserting the key into the lock cylinder. It consists of a door lock switch, actuator, and controller. 2. Function One is Central Control: When the driver locks the door beside them, all other doors are simultaneously locked. The driver can use the door lock switch to open all doors at once or open a single door individually. 3. Function Two is Speed Control: When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the doors by operating the door handles. 4. Function Three is Individual Control: Besides the door lock switch near the driver, other doors are equipped with separate spring lock switches, allowing independent control of each door's opening and locking.

The central locking module of the Wuling Hongguang S is usually hidden inside the driver's door panel, requiring removal of the interior trim to access it. When I dismantled the door panel myself, I found it clipped inside that black plastic box next to the window regulator, with a bunch of connector wiring harnesses attached. If replacing with a new module, pay attention to compatibility – last time my friend bought an aftermarket part at the auto parts market and ended up with a faulty locking system joke. Actually, besides the door panel, some base models might have it simplified near the steering wheel fuse box location, but most Hongguang S models keep it on the door panel. If DIY, always disconnect the first – those door panel clips are extremely brittle, and breaking them means spending extra on replacement parts.

My Wuling Hongguang S had a broken central locking system last year, and the mechanic said the driver's side door panel needed to be removed. Later, the repair bill showed that a part called the door lock control module was replaced, located above the inner steel panel of the door. I remember the mechanic mentioning that this component is most vulnerable to water damage, especially in older cars where the sealing strips have deteriorated, as rainwater can seep through the window gaps and easily short-circuit the circuit board. Now, when I wash my car myself, I avoid using high-pressure water jets near the window gaps. Additionally, I heard from the 4S shop staff that higher-end models with remote key fobs have more complex modules, and if the module fails, even the remote unlocking won't work, leaving you to use the mechanical key to open the door. The repair wasn't too expensive, with the module itself costing just over 200, and labor taking about an hour.

The central locking module in the Wuling Hongguang S is located inside the driver's side door panel. After removing the interior trim, you can see a small metal box about the size of a matchbox. Based on my experience replacing it twice: first disconnect the negative terminal, then use a plastic pry tool to start removing the panel from the bottom of the door, paying attention to the clip positions. The module is secured with three T20 screws - when unplugging the connector, pinch the clip instead of pulling hard. There are actually two common reasons for module failure: 1) door vibrations causing solder joints to crack, and 2) car wash water entering window gaps leading to connector oxidation. Keeping some WD-40 to spray on connectors can serve as an emergency fix. If having it replaced at a repair shop, remember to watch that they don't tear the door waterproof membrane.

Having studied the Wuling Hongguang's central control system, the module placement is quite deliberate. The standard location is inside the driver's door panel, closest to the lock motor, with signal wires running directly through the door hinge to the body. However, some older manual transmission models place it under the dashboard due to simpler door wiring. Functionally, this module controls the four door lock actions. If the left rear door fails to lock independently, it's likely a door lock motor issue. For DIY diagnostics, after removing the door panel, tapping the module casing can help—if the internal relay clicks, it's receiving power; no sound means the module needs replacement. A friend at a modification shop warned against parallel wiring aftermarket anti-theft devices with the original module circuits, as it can easily cause burnout.

Just helped my neighbor locate the central locking module for the Hongguang S last week - it's inside the driver's side door. First remove the handle screws, pry off the plastic trim panel, and you'll find the black metal box with heat sinks. Found the wiring harness trapped under waterproof membrane during disassembly - requires extra care when peeling it off. There are warning signs before failure: other doors locking slightly slower than driver's door during activation, or doors popping open after locking. An old mechanic taught me a trick: if the module fails after rain, blow hot air along door panel seams for 10 minutes with a hair dryer - usually moisture-induced short circuit. Permanent fix requires module replacement plus door resealing.
