Why Choose Our Pre-Programmed 2002-2005 Blazer BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. Each module is meticulously tested and loaded with your vehicle’s specific software using your VIN. This ensures perfect compatibility with the options and features your vehicle was built with. There is no core charge, so you can keep your original module. While the installation is primarily plug-and-play, some vehicles may require simple post-installation relearn procedures.
Post-Installation Information:
In some cases, additional steps may be needed after the BCM is installed:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on certain models.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your VIN at checkout, and the module will arrive ready to be installed in your vehicle.
What does the Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls functions like power windows, power locks, interior and exterior lighting, the security system, and even parts of the climate control system.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What if the airbag light comes on after I install the BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with a professional diagnostic tool.
Is this a difficult part to replace?
For most models listed, the BCM is located in the center dash or under the steering column and is accessible with basic hand tools. Since we pre-program it, the most complex part of the job is already done for you.
What if my original part number is not on your list?
The listed part numbers are the most common, but there may be others. Please contact us with your VIN, and we will be happy to verify compatibility for you.
