Restore Your Vehicle’s Electrical Systems
Are you battling frustrating electrical issues in your GM truck or SUV? Flickering lights, unresponsive power windows, or a climate control system with a mind of its own are common signs of a failing Body Control Module (BCM). This vital component acts as the central nervous system for your vehicle’s comfort and convenience features. This OEM-quality BCM, interchangeable with part number 15940214 and 25844480, is the definitive solution, arriving expertly programmed to your vehicle’s VIN for a straightforward, plug-and-play installation.
From the Diagnostic Bay
We recently had a 2009 Silverado in the shop with a list of bizarre symptoms. The owner complained of the radio turning off randomly, the driver’s side power window not working, and an intermittent airbag light. He had already replaced the window switch and checked fuses with no luck. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of chasing individual electrical gremlins, we installed a VIN-programmed BCM. In under 10 minutes, every single issue was resolved. It’s a perfect example of how a single module can fix a wide range of seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic climate controls (HVAC) and blower fan operation.
- ✔ Persistent airbag warning light on the dash, often with DTC B1001.
- ✔ Power windows, door locks, or interior/exterior lights that work intermittently or not at all.
- ✔ Vehicle security system malfunctions, leading to no-start or stalling conditions.
- ✔ A cluster of seemingly unrelated electrical issues and diagnostic trouble codes.
Solving Issues with Your Escalade ESV Body Control Module
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The key is our VIN programming service. We flash the module with the latest GM software specific to your vehicle before it ships. This means you can bypass a costly trip to the dealership for programming. Installation is typically quick, as the module is located under the driver’s side dash near the steering column. For most owners, it’s a simple swap. However, please be aware of potential post-installation procedures. If the airbag warning light remains on, a technician will need to perform an ‘SDM Key Sync’ with a professional scan tool. Some models may also require a ‘Brake Pedal Position Relearn’ to ensure all systems function correctly.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Is this module ready to install when I receive it?
Yes! We program the module to your vehicle’s specific VIN before shipping. This makes the installation process simple and eliminates the need for additional programming at a dealership.
What if my airbag light is on after I install this part?
If the airbag light appears, it’s usually because the new BCM needs to be synced with the airbag system’s SDM. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool.
Where is the BCM located on my truck or SUV?
On most compatible GM models like the Escalade, Silverado, and Tahoe, the BCM is located under the driver’s side dashboard, near the steering column.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your old module without any extra fees.
