End Frustrating Electrical Problems in Your GM Truck or Van
Are strange electrical issues making your Chevrolet Express, Silverado, or GMC Sierra unreliable? Flickering lights, unresponsive power windows, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). This central command unit is the brain behind your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and frustrating problems. Get your vehicle back to dependable, predictable operation with this direct-fit, VIN-programmed BCM.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing BCM is the likely culprit:
- Intermittent or non-working interior and exterior lights
- Power windows, door locks, or mirrors operating erratically or not at all
- HVAC controls and blower motor issues
- Security system malfunctions, leading to no-start conditions
- An airbag warning light on the dash, often with DTC B1001
- A variety of seemingly unrelated diagnostic trouble codes (DTCs)
This VIN Programmed GM 15136225 BCM is the definitive solution, engineered to restore full functionality without requiring a trip to the dealership for expensive programming. It arrives ready for a simple, plug-and-play installation.

Expert Insight: Why VIN Programming is Non-Negotiable
From over 20 years of hands-on diagnostics, I can tell you that a BCM is not a one-size-fits-all part. Each GM truck and SUV has a unique combination of optionsโfrom the sound system to the type of headlights. VIN programming is the crucial step that loads your vehicle’s specific configuration onto the module. Installing a non-programmed BCM from a salvage yard might seem cheaper, but it almost always leads to new, unpredictable problems because it’s configured for a different vehicle. Our VIN Programmed GM 15136225 BCM ensures every component works in harmony, just as the engineers intended, saving you from a world of diagnostic headaches.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can become unreliable.
Is this BCM truly “plug and play”?
Yes. Because we program the module to your vehicle’s VIN before shipping, it is ready for installation upon arrival. Simply disconnect the battery, swap the old module with the new one, and reconnect the battery. In most cases, no further steps are needed.
What if my airbag light stays on after installation?
If the airbag warning light is illuminated after installing the new BCM, it may require a simple sync procedure. A qualified technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” function to sync the airbag system with the new module. This is a quick procedure that resolves the light.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module, making the replacement process faster and more convenient for you.
How do I know this BCM is compatible with my vehicle?
This module is a direct replacement for multiple part numbers and fits a wide range of 2002-2007 GM trucks, vans, and SUVs. To confirm fitment, please use our vehicle compatibility tool or match one of the interchangeable part numbers listed on the product page to your original module. The key is providing your VIN so we can ensure our VIN Programmed GM 15136225 BCM is a perfect match.
