Is your Silverado, Sierra, or Express van plagued by bizarre electrical issues?
The Body Control Module, or BCM, is the central command center for your truck’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and instrument cluster functions. When the BCM starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems, making diagnosis a nightmare. Stop chasing individual component failures and address the root cause with our reliable, VIN-programmed replacement BCM.
We had a 2005 Silverado 2500 in the shop where the owner had already replaced the driver’s side window switch twice and was convinced the motor was next. The window would work intermittently, the dome light would flicker, and the key fob sometimes wouldn’t lock the doors. A quick scan showed multiple communication loss codes with the BCM. Instead of throwing more parts at it, we installed a VIN-programmed BCM. All the strange electrical gremlins vanished instantly. It wasn’t three separate problems; it was one central failure point.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more.
Is this part difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills, as it involves removing panels and swapping the module. The key benefit of our service is that the unit arrives pre-programmed, eliminating the need for dealership-level tools for initial setup.
How do I provide my VIN for programming?
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, as the programming is essential for the part to function.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if the airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be synced with the airbag system’s computer (SDM). A professional technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a high-level scan tool to resolve this.
