Is Your GM Vehicle Acting Possessed?
If you’re dealing with a frustrating array of electrical gremlins—from flickering lights and malfunctioning power windows to a car that won’t start—the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause widespread and confusing issues. This isn’t just an inconvenience; it can affect your vehicle’s security and drivability.
From the Diagnostic Bay
We once had a 2008 Chevy Impala come in that the owner called “Christine.” The dome lights would fade in and out while driving, the radio would change stations on its own, and the security light would flash randomly, sometimes preventing it from starting. The owner had already replaced the battery and checked grounds with no luck. A quick scan showed multiple communication loss codes with various modules. We identified the BCM as the weak link in the communication network. Installing a new, properly programmed GM Body Control Module solved every single issue at once. It wasn’t a ghost; it was just a faulty computer.
Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning security system or keyless entry.
- ✔ Instrument cluster warning lights (like the airbag or brake light) illuminating for no reason.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.
- ✔ Wipers or radio turning on and off by themselves.

Don’t waste time and money at the dealership. We provide a reliable, pre-programmed GM Body Control Module that’s ready for installation right out of the box. Simply provide us with your vehicle’s VIN during checkout, and our experts will flash the module with the latest GM-certified software specific to your car or truck. This ensures all your vehicle’s original features function correctly without requiring expensive dealer tools for programming.
This module is a direct replacement for a wide range of part numbers, including 15093910, 22860591, 25892622, and many more. Please verify your part number or vehicle fitment in the list provided.
Post-Installation Information
While our BCM is programmed for your VIN, some vehicles’ safety systems require a final handshake after installation. This is a simple process for any professional technician.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. 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 correct brake light operation and traction control functionality.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors dozens of body-related electronic functions. This includes power windows, door locks, interior/exterior lighting, security systems, wipers, and more.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. For a definitive diagnosis, a professional technician can use a scan tool to check for communication codes (U-codes) pointing to a faulty BCM.
What do you mean by ‘pre-programmed’?
It means we load the module with your vehicle’s specific software using your VIN before we ship it. This makes installation much simpler, as it eliminates the need for a trip to the dealership for initial programming.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit VIN (Vehicle Identification Number) to program the module correctly.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
