Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific configuration and security information onto the BCM. Without it, the module won’t recognize your vehicle’s options or keys, leading to system malfunctions or a complete failure to start. Our pre-programming service makes it a true plug-and-play part.
Is this module difficult to install?
Installation is generally simple for those with basic mechanical skills. The BCM is typically located under the steering column or dash. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, swapping it with the new one, and reconnecting everything. It can often be done in under 15 minutes.
My airbag light is on. Will this fix it?
A faulty BCM is a common cause of a persistent airbag light. While this module will fix the root cause, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to sync the new BCM with the airbag system and turn off the light post-installation.
Do I have to return my old BCM?
No. There is absolutely no core charge for this part. You can keep your old module, which simplifies the process and saves you the hassle and cost of return shipping.
Will this fit models other than the Silverado 2500?
Yes, this 2003-2007 Silverado 2500 Body Control Module is also a direct fit for a wide range of GM trucks and SUVs from that era, including the Sierra, Tahoe, Suburban, Yukon, Escalade, and Hummer H2. Please check the detailed fitment list to confirm compatibility with your exact vehicle.
