Are you battling frustrating and unpredictable electrical problems in your GM vehicle? A failing Body Control Module, or BCM, is often the culprit behind these baffling issues. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from power windows and locks to interior lighting and security systems. When it starts to fail, it can create a cascade of problems that are difficult to diagnose. This replacement BCM is the definitive solution to restore full electronic functionality to your vehicle.
This module is not just a replacement part; it’s a complete, ready-to-install solution. We professionally program the BCM with the latest GM software updates, specifically matched to your vehicle’s unique VIN. This critical step ensures seamless integration and communication with your vehicle’s other electronic systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we handle the rest.
From the Diagnostic Bay
We had a 2010 Chevy Tahoe in the shop that was driving its owner crazy. The radio would turn off randomly, the driver’s side power window would only work intermittently, and occasionally the security light would flash, preventing the truck from starting. We checked all the usual suspects—fuses, relays, and wiring—with no luck. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to a faulty BCM. Once we installed a VIN-programmed 2010 Tahoe Body Control Module, all the strange electrical gremlins vanished instantly. The customer was thrilled to have their reliable truck back.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the dashboard gauges or warning lights (e.g., security light, airbag light).
- ✔ Interior or exterior lights not working correctly or staying on.
- ✔ Problems with the keyless entry or anti-theft system.
- ✔ The radio or climate control system turning on and off by itself.
- ✔ A no-start condition where the engine cranks but won’t fire up due to a security fault.

Installation and Post-Install Procedures
Installation is typically straightforward, involving locating the old module (often under the steering column or behind the dash), disconnecting the battery, swapping the electrical connectors, and mounting the new unit. While this BCM is programmed to be plug-and-play, some vehicles may require additional steps after installation:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
Please note: This part replaces numerous part numbers, including 15892622, 20815898, 25847589, and many others listed in the fitment data. Verify your part number to ensure compatibility.
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, such as power windows, locks, lights, wipers, security systems, and interior accessories.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once, such as flickering dash lights, non-working power accessories, and security system faults. A diagnostic scan at a repair shop can confirm BCM failure by revealing specific communication error codes.
Is this BCM difficult to install?
For someone with moderate DIY skills, the physical replacement is generally not difficult. The main benefit of our service is that the module arrives programmed, saving you from needing specialized dealer tools for the most complex part of the job.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We will use this to program the BCM with the correct software and vehicle-specific options before shipping it to you.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
