Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Is this BCM difficult to install?
Installation is straightforward for most DIYers. The module is typically located under the driver’s side dashboard near the steering column. The process usually involves disconnecting the battery, unplugging the old module, plugging in the new one, and reconnecting the battery. It can often be done in under 15 minutes.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of return shipping.
Will this fix my airbag light?
A failing BCM can cause a false 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 systems and turn off the light after installation.
How do I know this is the right 2003-2007 Sierra 1500 Body Control Module for my truck?
You can verify the fitment by matching the part numbers listed in this description to your original module. When you place your order, we will ask for your vehicle’s VIN to ensure we program it correctly for your specific model and options, guaranteeing compatibility.
What if I still have issues after installation?
Our modules are rigorously tested and programmed to your VIN to ensure they work correctly. If you encounter an issue, please contact our expert support team. Occasionally, a secondary procedure like a brake pedal position relearn may be needed, or there could be another issue in the vehicle’s wiring that the BCM was being blamed for.
