Restore Full Electrical Function to Your SUV
Are you battling a vehicle possessed by electrical gremlins? Flickering lights, malfunctioning power windows, a horn that won’t work, or a dashboard that lights up with random warnings are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This replacement Body Control Module, part number 15122670, is the definitive solution to restore order and reliability to your vehicle.
This isn’t just a replacement part; it’s a complete, plug-and-play solution. We take the hassle out of the repair process by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This crucial step ensures that the BCM communicates flawlessly with all other computer systems in your truck, matching the exact options and configuration it had from the factory. By providing us with your VIN upon purchase, you receive a unit loaded with the latest GM software updates, ready for installation right out of the box.
Is Your 2005 SAAB 9-7X BCM Failing?
A faulty Body Control Module can manifest in numerous ways, often making diagnosis difficult for the average DIYer. If you’re experiencing any of the following symptoms, a failing BCM is the most likely culprit.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights that don’t work correctly or stay on.
- ✔ The horn sounding randomly or not working at all.
- ✔ Erratic instrument cluster behavior, including gauges that stop working.
- ✔ Security system issues or a vehicle that refuses to start.
- ✔ Inaccurate fuel gauge readings or other sensor-related problems.
- ✔ Communication errors with other modules, such as the Powertrain Control Module (PCM) or Transmission Control Module (TCM).
A Simple, Reliable Repair Process
We’ve streamlined the repair process to get you back on the road quickly. Simply locate your BCM (typically integrated with the fuse box on the driver’s side), disconnect the battery, swap the modules, and reconnect the battery. Because we handle the programming, you avoid a costly trip to the dealership for software flashing. In some cases, minor post-installation procedures may be required.
Post-Installation Procedures
While this module is designed to be a direct replacement, certain vehicle systems may need to be re-synced after installation.
- Airbag System Sync: If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on some models.
We also make the process affordable with a no core charge policy. You can keep your old module without any extra fees or the hassle of returning a core.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the horn.
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive pre-configured and ready for installation.
Where is the BCM located on my vehicle?
On most compatible models like the Trailblazer, Envoy, and Saab 9-7X, the BCM is integrated into the fuse box assembly, typically located under the rear seat on the driver’s side or near the driver’s side kick panel.
What if my airbag light is on after I install the new BCM?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Why do you need my VIN?
Your VIN allows us to program the BCM with the exact software and settings your vehicle requires. This ensures all features, from your power seats to your specific lighting configuration, work exactly as they did from the factory.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your original module without any additional fees or the need to ship it back to us.
