Fix Your Truck’s Electrical Headaches for Good
If you’re dealing with a 2003-2007 GM truck that seems to have a mind of its own—with flickering lights, a dead HVAC system, or power accessories that work one minute and not the next—you’ve likely met the common failure point: the Body Control Module (BCM). As the nerve center for your vehicle’s comfort and security features, a failing BCM can cause a cascade of frustrating issues. This replacement BCM, part number 10367690, is the definitive, hassle-free solution. We program it to your vehicle’s specific VIN before shipping, so it arrives ready for a true plug-and-play installation, getting your truck back to 100% without a costly trip to the dealership.
From the Diagnostic Bay
I remember a 2006 Silverado 2500 that rolled into my shop last month. The owner was at his wit’s end. The blower motor was dead, the radio would cut out, and the security light was flashing, causing an intermittent no-start. He’d already replaced the blower motor resistor and checked fuses, but the problems persisted. A quick scan showed a handful of communication codes, including the notorious BCM internal failure code B1001. After confirming the BCM was the culprit, we installed one of these pre-programmed units. In less than 10 minutes, every single one of his electrical gremlins was gone. It’s a common story, and this is the right fix.
Is Your Silverado Showing These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ The HVAC blower motor is inoperative or works intermittently.
- ✔ Power windows, door locks, or interior lights fail to operate correctly.
- ✔ The factory security system acts up, preventing the engine from starting.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔ You’re chasing strange electrical issues that have no other logical explanation.
- ✔ The vehicle’s horn or wipers activate on their own.
Your 5-Minute Path to a Fully Functional Truck
Installing your new 2003-2007 Silverado 3500 BCM is a straightforward job that most DIYers can handle with basic tools. Because we program it for you, the most complicated part of the job is already done.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and allow the system to reset.
- Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large electrical connectors.
- Swap the Modules: Carefully unplug the wiring harnesses from the old BCM. They have release tabs that need to be pressed. Remove any mounting screws or clips holding the old module in place, then install the new one in its place.
- Reconnect and Test: Plug the wiring harnesses firmly into your new BCM. Reconnect the battery terminal and start the vehicle. Test all functions: lights, locks, windows, wipers, and the HVAC system to confirm the repair.

Frequently Asked Questions
Do I need to program this BCM after I receive it?
No. This is the biggest benefit we offer. We program the module to your vehicle’s VIN before it ships, so it’s ready for installation right out of the box. This saves you a trip to the dealer and the high cost of programming fees.
Why is my airbag light still on after installation?
In some cases, the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). If the airbag light is on, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the two modules and resolves the light.
Is installation difficult for a DIYer?
Not at all. The BCM is typically held in place by a few clips or screws under the dashboard and is easily accessible. The entire swap usually takes less than 15 minutes, making it a very DIY-friendly repair.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any penalty.
What if my brake light or traction control light comes on?
This can occasionally happen. The system may require a ‘Brake Pedal Position Relearn’ procedure. This is another simple task that can be performed with a capable bidirectional scan tool to recalibrate the sensor and ensure all systems are communicating properly.
