Restore Your Vehicle’s Electrical System
Are you battling bizarre electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows, a dead battery overnight, or a persistent security light are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This module is the direct, reliable solution to get your vehicle operating correctly again.

Common Symptoms of a Failing BCM

- ✔ Interior dome lights or exterior lights staying on or not working at all.
- ✔ The security or anti-theft light is illuminated, and the vehicle may not start.
- ✔ Gauges on the instrument cluster behaving erratically or not working.

Installation and Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the steering column in trucks or in the center dash area for vans. After installing your new 2003-2007 GM BCM, some vehicles may require additional steps. If your airbag warning light illuminates, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position sensor relearn may be necessary to ensure proper brake light and stability control function. Always consult a factory service manual for your specific vehicle.

Frequently Asked Questions
How does the VIN programming service work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to flash the BCM with the exact software and calibrations your vehicle had when it left the factory, ensuring perfect compatibility.
Do I need to have this module programmed by a dealer?
No. The main benefit of our service is that the module arrives at your door pre-programmed and ready for installation. This saves you the time, cost, and hassle of a dealership visit.
What if my airbag light is on after I install the BCM?
This is a possibility on some models. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, requires a professional-grade scan tool and can be performed by most automotive repair shops.
Is this a new or used part?
This is a high-quality, genuine OEM part that has been thoroughly tested to ensure it meets or exceeds original performance specifications. It is not a new part, but it is a reliable and cost-effective alternative.
Where is the BCM located on my vehicle?
For most Silverado and Sierra pickups from this era, the BCM is located under the driver’s side of the dashboard, near the steering column. For Express and Savana vans, it is typically found behind the center dash panel.
