Are you battling frustrating electrical gremlins in your GM truck or van? Issues like erratic power windows, flickering interior lights, or a security system that prevents your vehicle from starting are often caused by a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing problems. This pre-programmed BCM is the definitive solution, designed to restore full functionality to your vehicle with minimal hassle.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork out of the repair by programming the module to your vehicle’s specific VIN before it ships. This means it arrives at your door with the latest GM software updates, ready for a direct-fit installation. You get a reliable repair without the need for an expensive trip to the dealership for programming.
Common Symptoms of a Failing GM BCM

Important Installation Notes:
While this module is designed for a simple installation, some vehicles may require additional steps after the part is installed. If the airbag warning light illuminates, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure correct brake light and traction control operation. Always consult a service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors dozens of body-related electronic functions, such as power windows, locks, lights, wipers, security systems, and more. It’s the command center for passenger comfort and convenience features.
Is this BCM difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located under the steering column or in the center dash. Since we pre-program the module to your VIN, you avoid the most difficult part of the process, which is the software setup.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your 17-digit Vehicle Identification Number (VIN). We must have this information to program the module correctly before we can ship it.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module, which can be helpful for double-checking part numbers or for any other diagnostic purposes.
What if my airbag light is on after installation?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this part fit my vehicle?
This BCM is a direct replacement for part numbers 15063578, 15081796, 15095334, and 19208537. It fits a wide range of 2002-2005 GM trucks and vans, including the Silverado, Sierra, Tahoe, Yukon, Astro, and S10/Blazer. Please verify the part number on your original module to ensure compatibility.
