Is your Chevrolet Suburban, Silverado, or GMC Sierra suffering from bizarre electrical issues? Power windows with a mind of their own, dashboard lights flashing randomly, or an HVAC system that won’t cooperate are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. This OEM-quality BCM, part number 15878753, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.

We handle the programming before it ships, so you can avoid a mandatory trip to the dealership. Simply provide your VIN at checkout, and we’ll ensure the module is ready for immediate installation and optimal performance right out of the box.
From the Diagnostic Bay
We had a 2008 Silverado 2500 in the shop with the owner at his wit’s end. The radio would turn off, the door locks would cycle while driving, and the A/C was dead. He had already replaced the battery and checked fuses. After a quick scan, we saw multiple communication loss codes pointing to the BCM. Before swapping the module, we did a quick check of the main ground on the frame under the driver’s door—a common weak point. It was clean. Installing a pre-programmed 2007-2011 Suburban 2500 BCM (the same part) took 10 minutes and instantly solved every single issue. Always check your grounds, but often, the module itself is the culprit.

Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before shipping. It arrives ready for a plug-and-play installation, saving you time and money.
What if my airbag light is on after installing the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag’s Sensing and Diagnostic Module (SDM). A technician can perform the ‘Setup SDM Primary Key’ function with a capable scan tool to resolve this.
Where is the BCM located on my truck?
The Body Control Module is typically found under the driver’s side of the dashboard, often near the steering column or emergency brake pedal.
Do I have to send my old BCM back?
No. This part is sold with no core charge, so you can keep your old module without any extra fees or hassle.
Will this fix my non-working power windows and door locks?
Yes, a faulty BCM is the most common cause for these issues. Replacing it with this pre-programmed unit is the correct repair for restoring power window, lock, and other accessory functions.
