Restore Your Truck’s Electrical System and Get Back on the Road
Are you battling frustrating electrical gremlins in your GM truck or van? Flickering lights, unresponsive power windows, a security system that won’t cooperate, or strange warning messages on your dash are all classic signs of a failing Body Control Module (BCM). These issues aren’t just an annoyance; they can sideline your vehicle and disrupt your work day. This is the definitive, hassle-free solution to restore your vehicle’s core functions and get you back to work with confidence.
Common Symptoms of a Failing BCM & Your Solution
The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing problems. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior dome lights or exterior lights staying on or not turning on.
- The security light is illuminated, and the vehicle won’t start (GM Passlock issues).
- Erratic or non-functional radio and climate controls.
- Diagnostic trouble codes (DTCs) related to communication errors (U-codes).

Expert Insight: Why BCMs Fail in Work Trucks
As a technician, I’ve seen countless 2003-2007 era GM trucks come in with these exact symptoms. These vehicles are workhorses, and their electronics are put through the wringer. BCM failure is often caused by years of voltage fluctuations from heavy-duty accessories, vibrations from rough job sites, or even minor water intrusion from a leaky windshield seal—a common issue. Replacing the BCM isn’t just about fixing a part; it’s about restoring the reliability you depend on. Our Programmed GM BCM 15136224 is the most efficient way to do just that, getting your truck back in service with minimal downtime.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, security system, and climate controls.
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM specifically for your truck’s factory options (like power seats, specific lighting, etc.). This ensures all features work correctly and makes the installation a true plug-and-play process, eliminating the need for dealer programming.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is very manageable. The BCM is typically located under the steering column or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, we always recommend consulting a service manual or a professional technician if you are unsure.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag light appears, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that a qualified repair shop can perform.
Will this fix my ‘Security’ light issue?
Yes, a failing BCM is one of the most common causes of GM’s Passlock security system issues, which often result in a ‘Security’ light and a no-start condition. Our Programmed GM BCM 15136224 is programmed to your VIN to correctly communicate with your vehicle’s anti-theft system, resolving this problem.
How do I know if this BCM is compatible with my truck?
