Are you experiencing frustrating electrical issues with your Cadillac CTS or other GM vehicle? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that won’t start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s electronic accessories. When it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s full functionality.
This is not just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific VIN before shipping, loading it with the latest software updates from GM. This critical service means you can avoid a costly trip to the dealership for programming, saving you time and money. Simply provide your VIN upon purchase, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on/off).
- ✔ Malfunctioning windshield wipers or climate control systems.
- ✔ “Service Theft System” or other security-related warnings on the dash.
- ✔ Instrument cluster gauges or warning lights behaving incorrectly.
- ✔ The vehicle fails to start despite having a good battery and starter.
- ✔ Key fob or remote entry system not working properly.

Installation and Post-Install Notes
While installation is straightforward for many, some vehicles may require additional steps to ensure all systems communicate correctly. After installing the new BCM, please be aware of the following potential procedures:
- 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: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process. This 2008-2013 CTS Body Control Module is also a direct replacement for numerous other part numbers and fits a wide variety of GM cars, trucks, and SUVs.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This saves you the time, hassle, and expense of a dealership visit.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have your VIN.
Is this a simple plug-and-play installation?
For the most part, yes. You disconnect the old module and connect the new one. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
What if my original part number is not 20864767?
This module is a replacement for dozens of different GM part numbers. Please check the detailed fitment list on this page. If your part number is on that list, this module will work for your vehicle.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it or dispose of it yourself, saving you the cost and effort of return shipping.
