In the glove compartment on the passenger side of the car, open it to see two plugs, which is the body control module. Damage to this module can cause some electrical components in the car to malfunction, such as lights, wipers, window lifts, door locks, etc. If damaged, it is necessary to consult a dealer promptly for inspection and repair. Below is related information: 1. Definition: The Body Controller (English: body-control-module, abbreviated as BCM), also known as the body computer (body-computer), in automotive engineering refers to the electronic control unit (ECU) used to control the body's electrical systems, and is one of the important components of a car. Common functions of the body controller include controlling power windows, power mirrors, air conditioning, headlights, turn signals, anti-theft locking systems, central locking, defrosting devices, etc. The body controller can be connected to other vehicle ECUs via a bus. 2. Role: The important task of the body controller is to simplify operations and reduce manual operations by occupants to avoid distracting them. The automotive body control system includes vehicle safety, comfort control, and information communication systems, mainly used to enhance the safety, comfort, and convenience of the vehicle.
The window control module of the Haima S5 is usually located inside the driver's side door, which is the door on your left when driving. You can see it by removing the interior trim panel, typically secured with plastic clips or screws. It's the core component that controls all window operations. The design places it there for the driver's convenience in one-touch control of all windows, positioned close to the window switches. If the main module fails, the entire window system may become inoperative. I've seen many owners complain about windows getting stuck, only to find out later that dust or water ingress caused a short circuit in the module. When inspecting, first disconnect the battery's negative terminal to avoid electric shock risks, then use a flat-head screwdriver to pry open the door trim panel, but be careful not to damage the plastic parts. The module is connected to wiring and motors, with common faults including loose wiring harnesses, corrosion, or burnt-out modules. For new cars, refer to the owner's manual for specific diagram locations, but older S5 models have similar placements. If you encounter issues, don't panic—it's safer to have a professional auto repair shop diagnose the problem, as DIY disassembly might worsen the situation.
I've driven quite a few cars, and the window control module of the Haima S5 is located on the inner side of the driver's door. When you're driving, the window switches are at your fingertips, while the module is hidden behind the door panel. It serves as the master switch for all window operations—if it fails, other windows might stop working. The design prioritizes driver convenience, hence its placement on the left side. Last time my window malfunctioned, the technician had to remove the door panel for repairs. The module connects via simple wiring but is prone to moisture damage. If rainwater seeps through window gaps, it can cause a short circuit. I recommend paying attention to door seals during car washes to prevent water accumulation. The Haima S5's module placement is similar to mainstream vehicles, making DIY repairs challenging; video tutorials are only suitable for experienced individuals. Module replacement isn't overly expensive, but installation requires care to avoid damaging wiring or door panel clips.
