Are you battling a frustrating array of electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause widespread and confusing issues. This genuine OEM-quality BCM, part number 15940214 (interchangeable with 25844480 and others), is the definitive solution to restore full functionality and peace of mind.
Is Your BCM Failing? Check for These Symptoms
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement is likely needed:
- ✔ Unresponsive or intermittent power windows, door locks, or mirrors.
- ✔ HVAC system failure, including a blower motor that won’t turn on or erratic temperature control.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Malfunctioning interior or exterior lights that stay on or won’t turn on at all.
- ✔ Security system problems, including random alarm activation or a no-start condition.
- ✔ Communication errors with other vehicle modules, leading to a variety of warning lights and DTCs.
From the Diagnostic Bay
We had a 2008 Sierra 2500 in the shop with the owner convinced his BCM was toast. The radio would cut out, the dash lights would flicker, and the power locks worked only half the time. Before ordering a part, we checked the G203 ground point behind the driver’s side kick panel. It was covered in corrosion. After a thorough cleaning and re-tightening the bolt, every single electrical issue disappeared. Always check your grounds before replacing a module—it can save you time and money.

This ensures that all factory settings and vehicle options are correctly configured, allowing for a true plug-and-play installation. You get to skip the costly trip to the dealership for programming, saving you time and hundreds of dollars.

Post-Installation Notes: In most cases, the installation is complete once the module is plugged in.

Similarly, a Brake Pedal Position relearn might be necessary on some models. Always consult a service manual for your specific vehicle’s requirements.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, door locks, interior/exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this part difficult to install?
No, for most DIYers, the installation is straightforward. The BCM is typically located under the driver’s side dashboard near the steering column. It’s held in by a few clips or bolts and has several electrical connectors. The entire process usually takes less than 15 minutes.
Will this pre-programmed BCM fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing it with this module will resolve the root cause. However, after installation, you may need a technician with a high-level scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new BCM with the airbag system and clear the light.
Do I need to send my old BCM back?
No, there is absolutely no core charge or need to return your old part. You can keep it or dispose of it at your convenience.
How do I ensure this part is compatible with my truck?
This module is compatible with a wide range of 2007-2013 GM trucks and SUVs. The best way to ensure compatibility is to match your original part number to one of the interchange numbers listed (like 25844480, 15940214, etc.) and provide your VIN during checkout for correct programming.
