Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module 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 instrument cluster. When it fails, these systems can become erratic.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to work in your truck.
Is this part difficult to install?
For most individuals with basic mechanical skills, the installation is straightforward. The BCM is typically located in or near the front fuse box. However, we always recommend consulting a service manual for your specific vehicle or seeking help from a qualified technician if you are unsure. This pre-programmed 2002-2005 Trailblazer BCM 15065293 eliminates the most difficult step, which is the software flashing.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is done with a professional scan tool using a procedure called ‘Setup SDM Primary Key in BCM’. This is a simple procedure for any professional repair shop if the light appears.
Do I need to send my old BCM back?
No. This purchase has no core charge. You can keep, recycle, or dispose of your original module at your convenience.
Will this fit my 2004 GMC Envoy XL?
Yes, this module fits a wide range of GM SUVs from this era, including the Envoy XL, Trailblazer EXT, Bravada, Rainier, and more. Please check the detailed fitment list on this page to confirm your exact year, make, and model.
