Is Your Vehicle Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows that have a mind of their own, or a security system that won’t cooperate? These frustrating and seemingly unrelated issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to your wipers and horn. When it starts to fail, it can create a cascade of bizarre electrical problems that are difficult to diagnose.
Don’t let a faulty BCM disrupt your driving experience. This listing is for a replacement Body Control Module, compatible with part number 13579004 and a wide range of other GM vehicles, that solves the problem without expensive dealership visits. We provide a straightforward programming service that makes installation a breeze.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ Security system or keyless entry malfunctions.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Wipers operating incorrectly or not responding to controls.
- ✔ Communication errors with other vehicle modules, often indicated by a professional scan tool.
Why Choose Our Programmed Chevy Volt BCM Service?
A new BCM from the dealership requires costly programming to sync it with your vehicle’s specific VIN and security information. Our unique service bypasses this complication entirely. By sending us your original BCM, we can perform a precise data transfer to the replacement unit. This cloning process ensures that the replacement module is a perfect electronic match for your car, retaining all original keys, security settings, and vehicle-specific options. The result is a true plug-and-play solution that saves you time, money, and the hassle of towing your vehicle to a dealer.
From the Diagnostic Bay
We had a 2012 LaCrosse come into the shop with the strangest set of symptoms. The customer said his radio would randomly change stations, the driver’s side window wouldn’t go down, and the alarm would go off in the middle of the night. He’d already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication fault codes pointing to the BCM. Instead of a complex rewiring job, we cloned his original BCM data onto one of our replacement units. After a 15-minute install, every single issue was gone. It’s a perfect example of how a single failing module can make a whole car seem possessed.

Post-Installation Information
While our programming service makes installation as simple as possible, some vehicles may require minor post-installation procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. This module is a direct fit for the part numbers listed, including 13579004, 13583450, 13580198, and more.
Frequently Asked Questions
What does the BCM actually do?
The Body Control Module (BCM) is a computer that supervises and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, security system, wipers, and comfort controls. It acts as a central hub for these systems.
Why do I need to send you my original BCM?
Your original BCM contains vital security data, your vehicle’s VIN, and specific option configurations. By transferring this data to the replacement module, we create a plug-and-play part that won’t require additional, expensive programming from a dealership.
Is this a difficult part to install?
The physical installation is typically straightforward. The BCM is often located in the kick panel, under the dash, or in the engine compartment. The main challenge is the electronic programming, which our service handles for you before you even receive the part.
Will I need to have my keys reprogrammed?
No. Because we are cloning the data from your original module, the replacement BCM will recognize your existing keys just like the original one did.
What happens if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
