Is your vehicle experiencing bizarre and frustrating electrical problems? You’re not alone.
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and even the instrument cluster. When the BCM starts to fail, it can cause a cascade of seemingly unrelated issues that are notoriously difficult to diagnose. This isn’t just an inconvenience; a faulty BCM can lead to a dead battery or a no-start condition, leaving you stranded.
This is a direct-fit replacement GM Body Control Module that solves these common failures. We take the guesswork and high dealership costs out of the equation. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your vehicle. This ensures a seamless installation process, getting you back on the road quickly and confidently.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security or anti-theft system light is on, preventing the car from starting.
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ Remote keyless entry failing to work.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
Why Choose a Pre-Programmed GM Body Control Module?
Replacing a GM Body Control Module used to require expensive diagnostic tools and a trip to the dealership for programming. Our solution simplifies the repair. By programming the module to your VIN before shipping, we eliminate the need for additional on-car procedures for most vehicles. This module arrives ready for installation, loaded with the latest vehicle-specific software from GM to ensure optimal performance and reliability. While the physical swap is straightforward, some vehicles may require a simple relearn procedure after installation.
Post-Installation Procedures
After installing your new BCM, one or more of the following procedures may be necessary depending on your specific vehicle and its options:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor relearn may be required.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Is this BCM really plug-and-play?
Yes, for most vehicles. We program it to your VIN, which handles the majority of the setup. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal sensor, which require a professional scan tool.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information.
What if my original part number is not 15093910 but is on the compatibility list?
If your original part number is on our list of compatible numbers, this module will work for your vehicle. GM often consolidates multiple part numbers into a single, updated replacement.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
Where is the BCM located on my vehicle?
The location varies by model. It’s commonly found under the driver’s side dash near the steering column, in the center dash, or behind the glove box. The fitment data on our page provides location details for many models.
