Is Your GM Truck Experiencing Strange Electrical Issues?
The Body Control Module (BCM) is the central command center for your truck’s body electronics. It manages a vast array of functions, including power windows, door locks, interior and exterior lighting, the security system, and even the horn. When the BCM starts to fail, it can create a host of confusing and frustrating problems that can seem unrelated. If your Silverado, Sierra, or other compatible GM vehicle is acting ‘haunted,’ a faulty BCM is a very likely culprit.
Common Symptoms of a Failing BCM
A failing Body Control Module can manifest in numerous ways. You might be experiencing one or more of the following issues, which point directly to a needed replacement:
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, not turning on, or flickering.
- ✔ The vehicle’s security or anti-theft system engaging randomly, causing a no-start condition.
- ✔ The horn honking unexpectedly or not working when you press it.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
- ✔ Key fobs failing to lock or unlock the doors.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical replacement is straightforward for a DIY mechanic, some electronic ‘handshake’ procedures may be necessary after installation.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be required to ensure proper operation of the brake lights and stability control systems.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process. With our pre-programming service and your VIN, you are getting the most streamlined repair process available.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It reads inputs from switches (like window switches or door locks) and controls outputs (like window motors, light bulbs, and lock actuators) to make those features work correctly.
Is this BCM ready to install right out of the box?
Yes! The main benefit of our service is that we flash the module with the latest GM software and program it to your specific VIN before we ship it. This makes it a true plug-and-play solution, eliminating the need for dealership programming.
Where is the BCM located on my 2013 Silverado 2500?
On most 2012-2014 GM trucks and SUVs covered by this part, the BCM is located under the dashboard on the driver’s side, typically near or attached to the steering column support.
My airbag light came on after I installed the new BCM. What do I do?
This is a normal security measure. The new BCM needs to be electronically introduced to the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to sync the modules and turn off the light.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship the module without it. Please double-check the VIN for accuracy before sending.
