Is Your SUV Plagued by Electrical Gremlins?
If you’re experiencing bizarre and frustrating electrical issues with your Saab 9-7X, Chevy Trailblazer, GMC Envoy, or other compatible GM SUV, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to your interior lights and security system. When it begins to fail, it can create a cascade of problems that are often difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Inaccurate or malfunctioning gauges on the instrument cluster.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Warning lights appearing on the dash, such as the airbag or brake light.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
The Direct-Fit, Programmed Solution for Your 2005 Saab 9-7X BCM
Don’t let a faulty BCM keep your vehicle off the road. This replacement Body Control Module is the definitive solution to restore full functionality to your vehicle’s electronics. The most significant advantage of our service is that we pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Your new BCM arrives ready for a straightforward installation.
Installation and Post-Install Considerations
The BCM is typically located inside the vehicle, often integrated with or near the interior fuse panel on the driver’s side. Physical installation is a matter of disconnecting the battery, removing the old module, and plugging in the new one. However, after installation, some vehicles may require additional electronic handshakes to ensure all systems communicate correctly.
- Airbag System Sync: If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure your brake lights and traction control system function as intended.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the brain for your car’s body electronics.
Do I need to program this module after I receive it?
No. We handle the programming for you. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your vehicle. It will arrive ready to install.
Where is the BCM located on my 2005 Saab 9-7X?
On the Saab 9-7X and related GM platforms like the Trailblazer and Envoy, the BCM is typically located inside the cabin as part of the front fuse box assembly, usually under the rear seat or on the driver’s side.
What happens if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this part compatible with part number 15122670?
Yes, this module is a direct replacement for several part numbers, including 15122670, 15065293, 15114669, 15191621, and 9352135.
What information do you need from me to program the BCM?
We require your 17-digit Vehicle Identification Number (VIN). This allows us to load the correct software and settings for your vehicle’s specific options and features. Please provide it during or after checkout.
