Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2003-2007 GMC Sierra 2500? Issues like erratic power windows, flickering lights, a non-responsive HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated problems. This OEM-quality replacement BCM, part number 15137395, is the definitive solution to restore your truck’s functionality and peace of mind.
Unlike a standard replacement, this module arrives at your door pre-programmed to your vehicle’s specific VIN. This crucial step ensures complete compatibility with your truck’s existing systems, eliminating the need for expensive and time-consuming programming at a dealership. It’s a true plug-and-play solution designed for a straightforward installation, getting you back on the road quickly.
From the Diagnostic Bay
We had a 2006 Silverado 2500 in the shop with a bizarre collection of issues: the radio wouldn’t turn off with the key out, the driver’s side power window worked intermittently, and the airbag light was on with a B1001 code. The owner had already replaced the window switch and checked grounds with no luck. After a quick scan, we identified communication errors pointing to the BCM. Instead of more guesswork, we installed a VIN-programmed module. In under 10 minutes, all the strange electrical issues were gone. It’s a perfect example of how a failing BCM can mimic multiple other problems, making it a critical component to check first.
Symptoms of a Failing Sierra 2500 Body Control Module

Frequently Asked Questions
What does “VIN Programmed” mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and all related factory software onto the module before shipping. This makes it ready for installation right out of the box, without needing a trip to the dealer for expensive programming.
Will I need to do anything after installing this BCM?
In most cases, it’s a plug-and-play installation. However, if your airbag light was on, a ‘Setup SDM Primary Key’ procedure may be needed with a professional scan tool to sync the new BCM with the airbag system. A brake pedal position relearn may also be required on some models.
Where is the BCM located on my 2005 Sierra 2500?
On most 2003-2007 GM trucks and SUVs like the Sierra, Silverado, and Tahoe, the Body Control Module is located under the driver’s side dashboard, near the steering column.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the repair process for you.
Will this fix an airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 diagnostic trouble code. Replacing the module with this pre-programmed unit is the correct fix for this issue, though a post-install sync procedure may be needed to clear the light.
