Are you battling frustrating electrical gremlins in your GM truck or van? Flickering dash lights, unpredictable power windows, or a security system that has a mind of its own are common signs of 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 cause a wide range of confusing and intermittent issues. Restore full functionality and peace of mind with our pre-programmed BCM, designed for a direct-fit replacement.
This module is professionally programmed to your vehicle’s specific VIN before shipping. This critical step ensures that the BCM communicates correctly with your truck’s other electronic systems, saving you a trip to the dealership and costly programming fees. Simply provide your VIN after purchase, and we’ll handle the rest, sending you a part that’s ready for installation right out of the box.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or anti-theft light flashing, preventing the engine from starting.
- ✔ Inconsistent or dead dashboard gauges and warning lights.
- ✔ Radio or climate control malfunctions.
- ✔ A ‘No Communication’ error when scanning with a diagnostic tool.

Post-Installation Information
While this module is programmed for plug-and-play installation, some vehicles may require minor post-installation procedures for full system integration:
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control system performance.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
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 electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM ready to install when I receive it?
Yes! We program the module to the VIN you provide, so it arrives ready to be installed without needing a trip to the dealer for programming. Some minor relearn procedures may be necessary after installation, as noted in the description.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
What if my airbag light comes on after installation?
This is a normal possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system. A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No, there is no core charge for this item. You can keep your original module.
Will this S10 Body Control Module fit other vehicles?
Yes, this BCM is compatible with a wide range of GM trucks and vans from 2002-2005, including the Blazer, Astro, Safari, Silverado, Sierra, and more. Please check the detailed fitment list on the page to confirm compatibility with your specific model.
