Global Hawk GX7 body control module is generally installed in the glove box, and the module has two plugs. BCM: BCM mainly controls the electrical appliances of the car body, such as the whole vehicle lights, wipers, washing, door locks, power windows, sunroof, power mirrors, remote control, etc. That is, the switch signals of these electrical appliances are input to the BCM, and the BCM directly or through a relay controls the corresponding electrical appliances to work. Body Controller: The body controller, also known as the body computer, in automotive engineering refers to the electronic control unit (ECU) used to control the body electrical system, which is one of the important components of the car.

My 2013 GX7 had its center console removed before. The body control module is located behind the trim panel under the driver's seat. If you bend down, you'll see a black square box with over a dozen wiring harnesses plugged into it - that's the one. Remember to disconnect the before working on it. Last time I forgot to disconnect it and nearly burned out the radio fuse. I recommend checking your vehicle's manual to confirm the location, as there might be differences between different model years. To remove the trim panel, you'll need to first take out two plastic clips. Use a flathead screwdriver to gently pry them loose, but don't use too much force or you might break the clips.

As experienced mechanics, when working on the GX7, we usually locate the body control module on the left side of the dashboard. Specifically, it's positioned inside the lower steering column cover – you'll need to lie in the driver's seat and look upward to spot that metal-finned box. The module is secured with two 10mm bolts, and the wiring harness connector has a foolproof design – never force it out. Critical reminder: Always disconnect the negative terminal before servicing, otherwise you risk frying the module or triggering airbag fault codes. Older vehicles have particularly brittle plastic clips, so keep some replacement clips handy during disassembly.

I just installed ambient lighting in my dad's GX7. The body control module is located inside the interior trim panel above the accelerator pedal. Lift up the felt sound insulation pad, and you'll see an aluminum alloy box with heat dissipation holes. If you're doing it yourself, prepare a T20 Torx screwdriver to remove the screws, and I recommend wearing safety goggles—last time plastic debris got in my eye and it hurt for hours. Before wiring, use a multimeter to check the voltage as the module draws a slight standby current. It's safer to add an independent fuse when modifying circuits.

This module is like the central nervous system of a car, controlling the windows, door locks, lights, and so on. In the GX7, it's usually hidden behind the trim panel on the left side of the steering column, positioned higher than in sedans so you don't need to crawl under the car. Out of curiosity, I opened it once: the casing had a BOSCH logo, and the green circuit board was integrated with relays and chips. The installation location is meticulously designed, with three layers of waterproof rubber padding added. When you encounter a malfunction, don't rush to replace the module—first, check if the F16 and F22 fuses are blown.

Personal lesson: A friend's GX7 window malfunctioned, and I watched the mechanic diagnose it at the repair shop. After reading the fault code with a decoder, they went straight to the driver's side, removed the knee guard, and found the module. It was located right behind the steering wheel adjustment lever, a metal box about the size of a palm. Repairing it required removing three screws from the air conditioning pipe bracket, which could take half an hour for someone unfamiliar. Later, it was discovered that the module's pins were corroded due to water ingress. The mechanic fixed it with rust remover. It's recommended to check the door drainage holes during the rainy season, as leaks are a common cause of module failure.
