Restore Your Truck’s Electrical Functions
Are you battling frustrating electrical gremlins in your GM truck or van? Flickering lights, unresponsive power windows, or intermittent door locks are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of confusing and unpredictable issues. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep you guessing. We offer a direct, reliable solution with this professionally programmed BCM.
From the Diagnostic Bay
We had a 2005 Sierra 2500 come in with a driver’s side power window that worked only when it wanted to. The owner had already replaced the switch and the window motor, but the problem persisted. After hooking up our diagnostic tool, we saw no communication from the driver’s door module commands at the BCM. Instead of throwing more parts at it, we installed a correctly programmed BCM. The window, locks, and interior lights immediately started working perfectly. It’s a classic case where the central ‘brain’ was the issue, not the individual components.
Symptoms of a Failing 2003-2007 Silverado BCM
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) staying on or not turning on.
- ✔ The security system acting erratically, causing no-start conditions or the alarm to go off randomly.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ Key fob not working to lock or unlock doors.
- ✔ Communication errors with other vehicle modules, triggering various warning lights.
A True Plug-and-Play Solution
This isn’t just a replacement part; it’s a complete service. We take the guesswork out of the repair by pre-programming this BCM specifically for your vehicle using your VIN. This ensures that all the factory settings and options your truck came with are correctly loaded into the module. We install the latest software updates from GM, which can resolve issues the original software may have had. This comprehensive programming means you get a module that is ready for installation right out of the box, saving you a costly trip to the dealership for programming.
This module is a direct replacement for a wide range of part numbers, including: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. Plus, there is no core charge, so you can keep your original module without the hassle of sending it back.
Post-Installation Procedures
After installing your new BCM, a couple of additional steps, known as relearn procedures, may be necessary to ensure all systems are communicating correctly. These are standard procedures when replacing a major electronic module.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be performed with a professional-grade bidirectional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration. This ensures your brake lights and traction control system function as intended.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories. This includes power windows, door locks, interior and exterior lighting, security systems, and wipers, among other things.
Is this BCM ready to install when I receive it?
Yes! This BCM is fully programmed to your vehicle’s specific VIN before we ship it. This makes the installation process much simpler, as you won’t need to have it programmed at a dealership.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. You can typically find your VIN on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
What if my airbag light is on after installation?
This is a common occurrence. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original part, which can be helpful if you ever need to reference it.
