Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re dealing with a 2003-2006 Chevrolet Tahoe where the electronics have a mind of their own, you’re not alone. Flickering lights, a dead HVAC panel, or power windows that refuse to work are classic signs that the Body Control Module (BCM) has failed. As the nerve center for your vehicle’s comfort and convenience features, a faulty BCM can make driving a daily frustration. This replacement BCM, compatible with part number 10367690, is the definitive solution to restore order and functionality to your vehicle.
A Technician’s Notebook: The Case of the Possessed Silverado
A customer brought in his ’05 Silverado 2500, convinced it was haunted. The radio would switch off, the dome light would stay on, and the driver’s window worked only when it wanted to. He’d already replaced the window switch and checked fuses, spending time and money with no result. After hooking up my scanner, I saw a handful of communication codes pointing to the BCM. Instead of a costly new module and a trip to the dealer for programming, we used our cloning service. We transferred his original BCM’s data to our replacement unit. An hour later, he drove away with every function working perfectly. This is the exact service we offer you—a direct, no-hassle fix.
Is Your Tahoe or Sierra Showing These Electrical Faults?
A failing BCM doesn’t always trigger a check engine light, but it leaves a trail of clues. If you’re experiencing any of the following, the BCM is the likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system acts up, causing a no-start condition or random alarm triggers.
- ✔ Headlights, taillights, or interior lights flicker or fail to turn on/off correctly.
- ✔ An airbag warning light is illuminated, sometimes with a B1001 diagnostic trouble code.
- ✔ Wipers operate randomly or not at all.
The Power of Our Cloning Service
Forget about expensive dealership visits and programming fees. Our unique Cloning Service makes this repair simple. Here’s how it works: you send us your original BCM. We expertly extract the vehicle-specific data—including settings for your options, mileage, and security information—and flash it directly onto this replacement module. We then ship both your original module and the ready-to-install replacement back to you. The result is a true plug-and-play component that your vehicle recognizes instantly, preserving all original functions without any additional steps. This is the most reliable and cost-effective way to replace your 2003-2006 Tahoe BCM.
Your 5-Minute BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: On most Tahoes, Yukons, and Silverados, the BCM is located under the driver’s side dashboard, to the left of the steering column. It’s a black box with several multi-pin connectors.
- ✔ Disconnect and Remove: Carefully press the release tabs on each electrical connector and pull them straight out. Then, unclip or unbolt the module from its mounting bracket.
- ✔ Install the New BCM: Seat the new, cloned BCM into the mounting bracket and firmly reconnect all electrical connectors until they click into place.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: windows, locks, wipers, lights, and HVAC to confirm the repair was successful.
Post-Installation Notes for a Perfect Repair
In some cases, additional steps may be needed. If your airbag light remains on, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a Brake Pedal Position Relearn might be necessary on certain models to ensure proper brake light and stability control operation. Always refer to a service manual for vehicle-specific instructions.

Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we transfer the complete software and vehicle-specific configuration data from your original, failing BCM to the replacement unit. This makes the new module an identical twin to your old one, ensuring it works perfectly with your truck’s existing systems without needing dealer programming.
Do I have to send my original BCM to you?
Yes, for the cloning service to work, we need your original module to read its data. We will return your original module along with the newly programmed replacement. There is no core charge.
Will this fix my intermittent wipers and erratic door locks?
Yes, in most cases. The BCM directly controls those functions. If your wipers, locks, windows, or HVAC system are behaving erratically, a faulty BCM is the most common cause, and this part is designed to resolve those issues.
What if my airbag light is on after I install the new BCM?
This can happen because the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be synced. A professional technician will need to use a scan tool to perform the “Setup SDM Primary Key in BCM” procedure to turn off the light.
Is part 10367690 the same as 15116066?
Yes, these part numbers are interchangeable. This module is a direct replacement for 10367690, 15116066, and many others listed in the fitment section, covering a wide range of GM trucks and SUVs.
