Is Your GM Truck or SUV Experiencing Bizarre Electrical Problems?
If you’re dealing with flickering lights, power windows and locks that have a mind of their own, or a security light that prevents your vehicle from starting, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s full functionality and reliability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We program the module with the latest GM software specifically matched to your vehicle’s VIN. This means you can skip the expensive trip to the dealership for programming. Simply provide us with your VIN after purchase, and we’ll ship a BCM that’s ready for a straightforward installation right out of the box.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The vehicle’s security system acting up, causing a no-start condition.
- ✔ Windshield wipers behaving erratically (e.g., won’t turn off).
- ✔ The radio or instrument cluster losing power or functioning incorrectly.
- ✔ False warning lights, such as the airbag or brake light, appearing on the dash.

Important Post-Installation Information
While our VIN programming handles the critical setup, some vehicles may require minor relearn procedures after installation. These can typically be performed with a high-end diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
There is no core charge for this module. You can keep your old part. Order today and get your vehicle’s essential electronic features working like new again.
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, including power windows, locks, lights, wipers, security systems, and the instrument cluster.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your vehicle had when it left the factory. This ensures compatibility and proper function of all your vehicle’s options.
Is this BCM difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located under the dash. Since we pre-program the unit, you avoid the most complex part of the job, which is the software flashing.
Will I need to do any programming myself?
No, the main programming is done by us before shipping. However, as noted, some vehicles may require simple relearn procedures for systems like the airbags or brake sensor, which may require a professional scan tool.
What happens if my airbag light is on after installation?
This indicates the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge, so you are not required to return your original module.
