Is Your GM Vehicle Plagued by Baffling Electrical Issues?
If you’re dealing with a car that seems to have a mind of its own—windows not working, dashboard lights flashing randomly, or a security system that prevents it from starting—the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your power locks and interior lights to the anti-theft system. When it fails, it can create a cascade of frustrating and seemingly unrelated problems. This listing is for a replacement BCM, part number 123589093, that is delivered to you fully programmed and ready for installation.
The Simple, Cost-Effective Solution: Mail-In Programming
Instead of purchasing a new, unprogrammed module and paying expensive dealership fees for calibration, our service provides a true plug-and-play solution. We take the vital information—including the VIN, mileage, and key data—from your original BCM and transfer it directly to this replacement unit. When you receive it, you simply install it, and your vehicle will recognize it as the original. No additional programming or dealer visits are required.

Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ Interior or exterior lights not working correctly (staying on or not turning on).
- ✔ Horn, wipers, or radio behaving erratically.
- ✔ Communication errors with other vehicle modules when scanned with a diagnostic tool.

Important Post-Installation Information
Our programming service makes installation straightforward, but some vehicles may require minor follow-up procedures. Please be aware of the following possibilities:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the BCM and the airbag’s SDM (Sensing and Diagnostic Module). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to resolve this. This is only necessary if the light is on.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be needed to ensure correct brake light operation and to satisfy the traction control system. This can also be performed with a capable diagnostic tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module (BCM) acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and more. It communicates with other modules to ensure everything works in harmony.
Why is your programming service better than just buying a used BCM?
A used BCM from another vehicle is programmed with that vehicle’s specific VIN and options. It will not work correctly in your car without being reprogrammed by a dealer, which is expensive. Our service clones your original data, making the replacement a true plug-and-play part that is matched perfectly to your vehicle’s configuration.
How long does the entire process take?
Once we receive your original BCM, our technicians typically complete the programming and ship the replacement unit back to you within 1-2 business days. Total turnaround time will depend on shipping speeds to and from our facility.
Is this part difficult to install?
The BCM is usually located under the dashboard on the driver’s or passenger’s side. Installation typically involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. It is a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual or professional if you are unsure.
What if I have an airbag light after installation?
If the airbag light comes on, it means the new BCM needs to be synchronized with the airbag module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a common step for this type of repair on many GM vehicles.
