Are you battling persistent electrical gremlins in your GM truck or SUV? A faulty Body Control Module (BCM) is often the culprit behind a host of frustrating issues, from malfunctioning power windows and door locks to erratic HVAC behavior and even no-start conditions. This genuine OEM-quality BCM, part number 10367690, is the definitive solution for a wide range of 2002-2007 General Motors vehicles, including the GMC Sierra, Chevrolet Silverado, Tahoe, and Suburban. It arrives expertly pre-programmed to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation without the need for a costly trip to the dealership.
We had a 2006 Sierra 3500 come in that was driving the owner crazy. The radio would turn on and off by itself, the dome light would flicker, and sometimes the truck just wouldn’t start. He’d already replaced the battery and checked the grounds. After scanning, we found a slew of communication error codes all pointing to one thing: a failing BCM. Swapping in a VIN-programmed module like this one resolved all the issues in under 10 minutes. It’s the central nervous system for the truck’s body electronics, and when it fails, it creates chaos.
Is Your GM Truck or SUV Showing These Symptoms?
- ✔ Unresponsive or intermittent power windows, door locks, or mirrors.
- ✔ HVAC controls not working or blower motor staying on or off.
- ✔ The security light is on, or the vehicle won’t start (Passlock issues).
- ✔ An airbag warning light is illuminated, often with a B1001 diagnostic trouble code.
- ✔ Interior or exterior lights behaving erratically—flickering, staying on, or not working at all.
- ✔ Wipers activating on their own or not responding to the switch.
Solving Electrical Problems with a Programmed 2003-2007 Sierra BCM
This isn’t just a replacement part; it’s a complete repair solution. The BCM is the command center for your vehicle’s comfort and convenience features. Our process ensures this module works perfectly with your truck from the moment you plug it in. We load the latest GM software updates based on your VIN, which often corrects factory flaws and improves performance. This eliminates common communication DTCs and restores full functionality to all related systems. Built to strict OEM specifications, this module guarantees reliable, long-term performance for your daily driver or work truck.
Installation is straightforward for any DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, unclip the electrical connectors from the old module, remove it, and install the new one. While most installations are simple, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light appears, which can be done with a professional scan tool. There is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does this Body Control Module do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, door locks, interior/exterior lights, the security system, wipers, and HVAC fan controls.
Is this BCM ready to install out of the box?
Yes. We pre-program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck’s other systems for a true plug-and-play installation, with no dealership visit required.
What if my airbag light is on after I install it?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool to clear the light.
Do I need to send my old BCM back?
No, there is no core charge or return required for this part. You can keep or dispose of your old module at your convenience.
Will this fit my 2005 Chevy Silverado?
Yes, this BCM fits a wide range of 2002-2007 GM vehicles, including the Chevrolet Silverado, Avalanche, Suburban, Tahoe, and Express Van, as well as the GMC Sierra, Yukon, Savana Van, Cadillac Escalade, and Hummer H2. Please check the full fitment list to confirm compatibility.
