Are you battling frustrating electrical gremlins in your GM truck or SUV? Intermittent power windows, flickering lights, a stubborn security system, or gauges that have a mind of their own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it falters, it can cause a cascade of confusing and unpredictable issues. This module is the direct-fit, reliable solution to restore order and get your vehicle’s features working correctly again.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealership hassle out of the equation by pre-programming this BCM to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures seamless integration with your truck’s existing systems. Simply provide your VIN after purchase, and we’ll handle the complex programming, loading the latest GM software updates for optimal performance.

Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) working intermittently or not at all.
- ✔ The security light stays on, preventing the vehicle from starting (Passlock issues).
- ✔ Instrument cluster gauges behaving erratically or going dead.
- ✔ Radio, HVAC, or climate control systems malfunctioning.
- ✔ False warning messages like “Service Vehicle Soon” on the dash.
- ✔ Unexplained battery drain when the vehicle is off.
Installation and Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the steering column. Once installed, while our programming handles the majority of the setup, some vehicles may require a couple of simple relearn procedures.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform a “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
There is no core charge for this part. You can keep your old module.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls various electronic accessories, such as power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to program this BCM?
No. This BCM comes fully programmed to your vehicle’s VIN before we ship it. This makes the installation process much simpler, as it’s ready to be installed right out of the box.
Where is the BCM located on my 2002 Yukon or Silverado?
On most compatible models like the 2002 Yukon, Silverado, and Sierra, the BCM is located under the driver’s side dashboard, near the steering column.
What happens if my airbag light is on after installation?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU, ensuring wide compatibility across many GM models.
