Tired of Your Truck’s Electrical Gremlins?
Are strange and frustrating electrical issues plaguing your 2003-2007 GM truck or SUV? One moment the power windows work, the next they don’t. The HVAC blower motor has a mind of its own, or a persistent airbag light refuses to go away. These aren’t just minor annoyances; they’re signs that the central command center for your vehicle’s body electronics—the Body Control Module (BCM)—is failing. This isn’t a problem you have to live with. We offer a reliable, permanent fix with our professionally programmed BCM, designed to restore order and make your vehicle dependable again.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of confusing problems. If you’re experiencing any of the following, this module is the solution you need:
- Intermittent or non-working power windows, door locks, or interior/exterior lights.
- HVAC control problems, including a blower that won’t turn on or operates erratically.
- An active airbag warning light, often accompanied by Diagnostic Trouble Codes (DTCs) like B1001.
- Security system malfunctions that can lead to a no-start condition.
- Wipers that behave unpredictably or fail to operate.
- A variety of other body-related DTCs that point to a communication failure.

The issue wasn’t the individual components; it was the BCM failing to send the correct commands. By replacing the BCM with a properly programmed unit like this one, you’re not just fixing a part—you’re addressing the root cause of the electrical chaos, saving you from future headaches and unnecessary repairs.
This module is a direct replacement for a wide range of part numbers, including 15116066, 15136225, 15194170, 15198116, and more.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine-related electronics. It manages functions like power windows, power door locks, the security system, interior and exterior lighting, wipers, and the HVAC blower controls. When it fails, these systems can become erratic or stop working altogether.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s specific VIN before it ships. This ensures it is ready for installation right out of the box without requiring any additional programming from a dealership, making the process as simple as possible.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). If the airbag light remains on, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. This is a quick process that syncs the modules.
Do I need to send my old part back?
No. There is no core charge or deposit associated with this part. You can keep or dispose of your old module without any hassle.
How can I be sure the BCM is my problem?
While this part fixes the common symptoms listed, a proper diagnosis is always recommended. If multiple, unrelated electrical systems are failing intermittently (e.g., windows, locks, and radio), the BCM is a very likely culprit. A diagnostic scan for B-codes (Body Codes) can often confirm a BCM failure.
Will this fit models other than the Silverado?
Absolutely. This BCM is compatible with a wide range of 2003-2007 GM trucks and SUVs, including the GMC Sierra, Chevrolet Tahoe/Suburban, GMC Yukon, Cadillac Escalade, and Hummer H2. Please verify the part number or check the compatibility list to ensure it’s the right fit for your specific vehicle.
