Are you battling strange and frustrating electrical issues in your GM truck or van? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of unpredictable symptoms. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process simple. This module is not just a replacement part; it’s a complete, programmed solution. Upon purchase, simply provide us with your vehicle’s VIN. Our experts will then flash the module with the latest GM software specific to your vehicle’s configuration. This means it arrives at your door ready for installation, eliminating the need for an expensive trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers turning on by themselves or not responding to the switch.
- ✔ Warning lights on the dashboard with no apparent cause.
- ✔ Rapid battery drain while the vehicle is off.
Guaranteed Fitment and Simple Installation
This module is a direct replacement for a wide range of GM vehicles from the early 2000s. By programming it to your VIN, we ensure it communicates perfectly with your vehicle’s other systems. This specific 2002-2005 GMC Safari BCM is also the correct part for many Chevy Astro, Silverado, Sierra, Tahoe, and Suburban models. It directly replaces part numbers including 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU.
While the installation is primarily plug-and-play, some vehicles may require minor post-installation procedures. For example, if your airbag light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool will sync the systems. Similarly, a brake pedal position relearn might be needed. These steps are straightforward for any qualified technician.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready to install.
What does the Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s electronic accessories, such as power windows, locks, lights, wipers, security system, and more. It acts as the central hub for these functions.
Is this a true plug-and-play part?
For most vehicles, yes. Because it’s pre-programmed, you can simply install it. However, in some cases, additional relearn procedures like an airbag system sync or brake pedal position relearn may be required using a diagnostic tool.
How do I confirm this is the right part for my vehicle?
The best way is to match the part number from your original BCM to one of the numbers listed: 15063578, 15081796, 15095334, 19208537, DKAK, or DPNU. You can also use the extensive fitment list provided on this page.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s computer (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
