Restore Full Electrical Function to Your GM SUV
Are you battling frustrating and unpredictable electrical problems in your vehicle? Issues like erratic power windows, malfunctioning door locks, intermittent wipers, or confusing instrument cluster behavior are often signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can create a cascade of annoying and potentially unsafe issues. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a seamless installation process.
Is Your 2005 SAAB 9-7X BCM Failing?
A faulty BCM can manifest in numerous ways, often being misdiagnosed as individual component failures. Before you replace another switch or motor, check if your vehicle is exhibiting any of the common symptoms of BCM failure. This module is the key to resolving those persistent electrical gremlins.
Common Symptoms of a Bad BCM:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) staying on, flickering, or not turning on.
- ✔ The security system or keyless entry malfunctioning or setting off false alarms.
- ✔ Wipers behaving erratically, not parking correctly, or not working.
- ✔ Warning lights on the dashboard illuminating for no apparent reason.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition in some cases.
- ✔ Inaccurate readings on the instrument cluster gauges.
Plug-and-Play Solution with VIN Programming
The biggest hurdle in replacing a modern vehicle computer is the need for expensive, dealer-level programming. We eliminate that step entirely. When you purchase this module, simply provide us with your vehicle’s 17-digit VIN. Our technicians will flash the unit with the latest official GM software and calibrations specific to your exact vehicle build. This ensures that all factory-installed options and systems are recognized and function correctly right out of the box. You receive a part that is truly ready for installation, saving you time, money, and a trip to the dealership.
Installation and Post-Install Procedures
This BCM is typically located on the side of the front interior fuse box. While the physical replacement is straightforward for a DIYer with basic tools, some vehicles may require simple electronic relearn procedures after installation. These are not full programming steps but are necessary to sync the new module with other systems in the vehicle.
- Airbag System Sync: If your airbag warning light is on 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 module.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on some models.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install.
Where is the BCM located on my 2003 GMC Envoy?
On most GMT360 platform vehicles like the Envoy, Trailblazer, and Rainier, the BCM is integrated with or attached to the side of the interior fuse panel, typically located under the rear driver’s side seat or on the driver’s side of the center console.
What happens if my airbag light is on after I install this part?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s Sensing and Diagnostic Module (SDM). A mechanic with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this part difficult to install myself?
The physical replacement is generally simple, involving disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. However, be aware that post-installation relearn procedures for the airbag or brake systems may require a scan tool.
What part numbers does this BCM replace?
This unit is a direct replacement for part numbers 15122670, 15065293, 15114669, 15191621, and 9352135.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
