Restore Full Functionality to Your GM SUV or Truck
Are you chasing down frustrating electrical issues in your 2003-2006 Chevrolet Tahoe? One day the power windows work, the next they don’t. Maybe your HVAC controls have a mind of their own, or you’re seeing a persistent airbag light. These seemingly random problems often point to a single culprit: a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can wreak havoc, making your reliable truck feel unpredictable. This module, part number 15137394, is the direct-fit solution to restore order and dependability.
We solve the biggest headache of module replacement: programming. This BCM comes with our expert Cloning Service. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data to this replacement unit. The result? A truly plug-and-play module that requires no expensive trips to the dealership for programming. It will work seamlessly with your existing keys and security system right out of the box, saving you time, money, and hassle.
From the Diagnostic Bay
I remember a 2005 Tahoe that came into my shop with a laundry list of complaints from the owner. The radio would cut out, the driver’s side door lock was unresponsive, and the security light would flash intermittently, sometimes causing a no-start condition. The owner had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I saw a slew of communication DTCs pointing to the BCM. These modules are notorious for internal solder joint failures over time, leading to these exact kinds of ‘ghost’ problems. By installing a cloned 2003-2006 Tahoe BCM, we had all systems back online in under 10 minutes. The customer was thrilled to have his truck back to normal without a massive dealership bill.
Is Your Tahoe Showing These Electrical Gremlins?
A failing BCM doesn’t always cause a complete failure. It often starts with intermittent issues that can be difficult to diagnose. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system acting up, leading to a no-start or crank-no-start situation.
- ✔ An illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Unpredictable behavior from windshield wipers or other accessories.
- ✔ A network of communication codes stored in various modules.
A Straightforward Guide to Your BCM Swap
Thanks to our cloning service, installing your replacement BCM is a simple job that most DIYers can complete in their driveway. No special tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most 2003-2006 Tahoes and similar GM models, the BCM is located under the driver’s side dashboard, near the steering column. It’s a black plastic box with several large electrical connectors.
- Remove the Old Module: Carefully unplug the electrical connectors. They have release tabs that need to be pressed. Once disconnected, unclip or unbolt the module from its mounting bracket.
- Install the New Module: Seat your cloned replacement BCM into the mounting bracket and securely plug in all the electrical connectors until they click into place.
- Reconnect and Test: Reconnect your battery terminal. Start the vehicle and test all functions—windows, locks, lights, HVAC, etc.—to confirm the repair was successful.

Frequently Asked Questions
How does the Cloning Service work?
After you place your order, you will receive instructions on how to ship your original BCM to us. We then use specialized equipment to read the unique data from your module and write it directly onto the replacement unit. This ensures 100% compatibility with your vehicle’s features and security system.
Do I need to send my original BCM? What about a core charge?
Yes, for the cloning service to work, we need your original module to extract the data. There is no core charge, and we always return your original module to you along with the newly programmed replacement.
Can I install this myself if I’m not a mechanic?
Absolutely. The physical installation is very straightforward, typically taking less than 15 minutes with basic hand tools. Since our cloning service handles all the programming, it’s a simple plug-and-play process, perfect for a DIY repair.
What if my airbag light stays on after installation?
In some cases, the BCM and the airbag system (SDM) need to be re-synced. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a technician with a professional-grade scan tool. This is only necessary if the light appears after the swap.
What is the warranty on this part?
This module is backed by a one-year warranty, giving you peace of mind that you’re installing a quality, dependable part that will last.
