Are strange electrical problems in your GM truck or van causing constant frustration?
Flickering lights, power windows with a mind of their own, or a security system that randomly acts up are all classic signs of a failing Body Control Module (BCM). These issues can disrupt your workday and make your vehicle feel unreliable. Don’t let electrical gremlins keep you off the road. This module is the definitive solution, designed to restore your vehicle’s core functions and get you back to work with confidence.
Common Symptoms of a Failing BCM & Your Direct Solution
If you’re experiencing any of the following, a faulty BCM is the most likely culprit:
- Inoperative or erratic power windows, door locks, and mirrors.
- Interior dome lights or exterior lights staying on or not working at all.
- The security or anti-theft system (Passlock) preventing the engine from starting.
- Warning lights appearing on the instrument cluster for no reason.
- Communication errors (U-codes) when scanned with a diagnostic tool.

Expert Insight: Why Pre-Programming is a Game-Changer
From the shop floor, we can tell you that a BCM is the central command for your truck’s body electronics. It’s not a simple relay; it’s a computer that must communicate perfectly with your engine computer, instrument cluster, and anti-theft system. Without being programmed to your specific VIN, these components can’t recognize each other, leading to a no-start condition or a dashboard full of warning lights. By programming this 2003-2007 GM BCM 15136224 for you, we handle the most critical and complex step, turning what would be a dealership-level repair into a straightforward component swap for you or your mechanic.
Frequently Asked Questions
Do I need to send you my old BCM?
No. This Body Control Module is sold without any core charge. You can keep your original part, saving you the time and hassle of a return shipment.
Is this part truly ‘plug and play’?
Yes, for the most part. Because we program the module to your VIN, it is ready to be installed and will communicate with your vehicle’s other systems. However, in some specific cases, a post-installation procedure like an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be necessary with a professional scan tool to clear related warning lights.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the BCM correctly for your specific truck or van.
How do I know for sure that my BCM is the problem?
Common signs include multiple, unrelated electrical issues like faulty power locks, erratic interior lights, and security system problems. While these are strong indicators, we always recommend having a qualified technician perform a full vehicle diagnostic to confirm the BCM is the source of the issue before ordering a replacement 2003-2007 GM BCM 15136224.
What happens if the airbag light comes on after installation?
If the airbag warning light is on after installing the new BCM, it means the module needs to be synced with the airbag system. A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade diagnostic tool to resolve this.
