Fix Your Truck’s Electrical Headaches for Good
Are you chasing down bizarre electrical problems in your Chevy Silverado? One day the power windows don’t work, the next the radio acts possessed, and the dashboard is lit up with random warnings. As a technician with over two decades of experience, I’ve seen this countless times. The Body Control Module (BCM) is the electronic nerve center for your truck’s accessories, and when it starts to fail, it can cause a cascade of frustrating, hard-to-diagnose issues. This OEM-quality Body Control Module, part number 10367690, is the definitive solution for your 2003-2007 Silverado 2500 BCM problems. It arrives pre-programmed to your truck’s specific VIN, eliminating the need for expensive dealership visits and getting you back on the road with confidence.
A Technician’s Notebook: The Intermittent No-Start
A customer brought in his ’05 Silverado 2500 work truck. The complaint was an intermittent no-start. The battery was new, the starter tested fine, but sometimes it just wouldn’t crank. He’d also noticed his security light would flash randomly. After checking the basics, I hooked up my scanner and saw a U-series communication code and a BCM internal fault. The failing BCM wasn’t properly communicating with the security system and powertrain module. We swapped in a VIN-programmed BCM, and the problem was solved instantly. It’s a classic failure mode for these trucks, where a single module causes symptoms that point in a dozen different directions.
Is Your Silverado Showing These Symptoms?
A failing BCM doesn’t always throw a clear code. If you’re experiencing any of the following, this module is likely the culprit:
- ✔ Flickering interior or exterior lights, or lights that won’t turn off.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor runs erratically.
- ✔ The security system malfunctions, causing no-start or crank-no-start conditions.
- ✔ An airbag warning light on the dash, often with a DTC like B1001 (Option Configuration Error).
- ✔ Unexplained battery drain that leaves you stranded.
- ✔ Diagnostic trouble codes related to communication or body systems.
A Straightforward Guide to Installation
Replacing the BCM is a job most DIYers can handle in their driveway in under 15 minutes. Our pre-programmed module makes it a true plug-and-play repair.
- Safety First: Always disconnect the negative terminal from your truck’s battery to prevent electrical shorts and allow the system to reset.
- Locate the BCM: On most 2003-2007 Silverado 2500 models, the BCM is located under the driver’s side of the dashboard, to the left of the steering column. It’s a black box with several large multi-pin connectors.
- Swap the Module: Carefully unplug the connectors from the old BCM. They have locking tabs, so be gentle. Unbolt or unclip the old module and install the new one in its place.
- Reconnect and Test: Securely plug all connectors into your new BCM. Reconnect the battery terminal. Turn the key to the ‘On’ position and test all functions—lights, windows, wipers, locks, and HVAC.
- Post-Installation Checks: In some cases, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a professional scan tool if the airbag light stays on. This syncs the new BCM with the airbag system.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you time and the high cost of dealership programming.
Is there a core charge for my old part?
There is no core charge. You can keep your old module without any hassle or need to return it.
What tools do I need for installation?
Typically, you only need basic hand tools like a socket wrench or nut driver to remove the mounting bolts and a flathead screwdriver to help release connector tabs. The entire process usually takes less than 15 minutes.
My airbag light is on after installing the new BCM. What should I do?
This is uncommon but can happen. It means the new BCM needs to be electronically introduced to the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a bi-directional scan tool to resolve this.
Will this fix my truck’s security system issue?
Yes, a faulty BCM is a very common cause of security system problems, including Passlock failures that result in a no-start condition. Replacing it with this programmed module will restore proper communication and function.
