Are you chasing frustrating electrical gremlins in your GM truck or van? A faulty Body Control Module (BCM) is often the culprit behind a wide range of baffling issues that can make your vehicle feel unreliable. This replacement BCM, part number 15194169, is the direct solution to restore full functionality and peace of mind. It arrives pre-programmed to your vehicle’s specific VIN, ensuring a straightforward installation process and compatibility with your existing systems.
From the Diagnostic Bay
We had a 2006 Silverado 2500 in the shop that was driving the owner crazy. The radio would turn on by itself, the power locks worked intermittently, and the security light would flash, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After hooking up our scanner, we saw multiple communication errors pointing towards the BCM. Instead of a complex and expensive diagnostic chase, we installed a VIN-programmed BCM. All the strange electrical issues vanished instantly. It’s a common failure point that can mimic a dozen other problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Dashboard warning lights flickering or staying illuminated for no reason.
- ✔ “Service Theft System” or other security-related messages on the dash.
- ✔ Interior dome lights or exterior lights not working correctly.
- ✔ The horn or windshield wipers activating unexpectedly.
- ✔ Intermittent no-start conditions due to the anti-theft system.
- ✔ Communication loss with other vehicle modules.
Solving Issues with Your 2003-2007 Silverado BCM
Don’t let a faulty module dictate how your truck behaves. This replacement BCM is the definitive fix for the issues listed above. We take the guesswork out of the repair by programming the module with the latest GM software updates using the VIN you provide. This means the module is ready for installation right out of the box, saving you a trip to the dealership and expensive programming fees. Plus, with no core charge, you don’t have to worry about the hassle and expense of sending your old part back.
Important Post-Installation Information
While this module is programmed for your vehicle, some GM security and safety systems may require a simple sync procedure after installation. Please be aware of the following:
- Airbag System Sync: If the 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 required to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation or post-installation process.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that acts as a central hub for controlling body electronics. This includes power windows, locks, lights, wipers, the security system, and more. When it fails, these systems can behave erratically.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options. This ensures it communicates properly with the other modules in your truck or van, making the installation process much smoother.
Is this part difficult to install?
The physical installation is typically straightforward, involving the removal of a few trim panels to access the module (usually under the steering column or in the center dash). However, as noted, some post-installation electronic procedures like an airbag sync may be required, which necessitates a professional-grade scan tool.
What happens if my airbag light is on after installing the BCM?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag’s Supplemental Inflatable Restraint (SIR) module. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module without needing to send it back to us.
