Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your truck or SUV? Flickering lights, unresponsive power windows, a malfunctioning security system, or an HVAC system with a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and disruptive problems. This OEM-quality replacement BCM, part number 15878753, is the definitive solution for a wide range of 2007-2013 General Motors vehicles, including the Cadillac Escalade, Chevrolet Silverado, GMC Sierra, and more.
From the Diagnostic Bay
We had a 2010 Silverado 2500 in the shop that was driving its owner crazy. The radio would cut out, the dome light would flicker, and the A/C blower was completely dead. The owner had already replaced the blower motor resistor with no luck. After scanning, we found a handful of communication codes pointing to the BCM. Upon replacement, we made sure to clean the main grounding point under the dash as they are notorious for causing intermittent issues. With the new VIN-programmed BCM installed and a solid ground, all the phantom electrical issues vanished. It’s a reminder that a good part and a good ground are both essential for a successful repair.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This allows for a simple, plug-and-play installation without requiring any additional dealership programming, saving you time and money.
Where is the BCM located on my vehicle?
On most compatible GM trucks and SUVs like the Escalade, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column. Physical installation typically takes only a few minutes.
My airbag light is on after installing the new BCM. What should I do?
If the airbag light is on, it means the new BCM needs to be synced with the airbag system’s SDM. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed using a professional-grade diagnostic scan tool.
Is this a new or used part?
This is a high-quality, OEM-standard replacement part that has been tested and prepared with new programming to ensure it performs reliably. It is backed by our one-year warranty.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us, making the process hassle-free.
