Restore Full Electrical Control to Your GM Truck or SUV
Are you battling bizarre electrical issues in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Intermittent wipers, flickering lights, unresponsive power windows, or a malfunctioning HVAC system are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This OEM-quality replacement BCM, part number 15263363 (interchangeable with 25844480 and others), is the definitive solution to restore your vehicle’s functionality and peace of mind.
This module arrives pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN), ensuring a seamless, plug-and-play installation. By programming the unit with the latest GM software updates, we eliminate the need for an expensive trip to the dealership for coding. Simply install the module, and you’re ready to go. It’s the most efficient and reliable way to get your truck or SUV back on the road and working correctly.
From the Diagnostic Bay
We had a 2008 Sierra 2500 come in that was driving the owner crazy. The radio would turn off randomly, the driver’s side power window wouldn’t work, and the airbag light was on with a B1001 code. The owner had already replaced the window switch and checked every fuse he could find. After a quick scan, we saw multiple communication errors pointing to the BCM. A common point of failure on these trucks is the ground connection near the BCM. We checked it, and while it was okay, we knew the module itself was the culprit. We installed one of our VIN-programmed BCMs, performed the quick SDM key sync with our scanner to clear the airbag code, and the truck was flawless. It’s a reminder that many electrical gremlins often lead back to one central component.
Symptoms of a Failing 2007-2011 Yukon Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your BCM needs replacement:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Malfunctioning HVAC controls, including an inoperative blower fan or incorrect temperature blending.
- ✔ An illuminated airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system issues, including false alarms or a no-start condition.
- ✔ Intermittent operation of windshield wipers and washers.
- ✔ Communication errors with other vehicle modules, leading to various warning lights on the dash.
Installation and Post-Install Procedures
Replacing the BCM is a straightforward process for most DIY mechanics. The module is typically located under the driver’s side dashboard, near the steering column. The physical installation can often be completed in under 15 minutes. However, because this module communicates with critical safety systems, some post-installation steps may be required.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade bidirectional scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some models, a brake pedal position sensor relearn might be needed to ensure proper brake light and traction control functionality.
- No Core Charge: We do not require you to return your old part. There is no core charge, saving you time and hassle.
This module is a direct replacement for a wide range of GM vehicles from 2007-2013 and is interchangeable with numerous part numbers, including: 25835966, 15263497, 15878753, 15943678, 25790508, 25844479, 20939137, and 22860591. Please verify fitment for your specific vehicle before ordering.
Frequently Asked Questions
What does a Body Control Module do on my GMC Yukon?
The BCM acts as the central computer for your Yukon’s non-engine related electronic systems. It manages functions like power windows, door locks, interior and exterior lighting, the security system, climate controls, and wipers, ensuring they all work together correctly.
What does “VIN Programmed” mean for this BCM?
“VIN Programmed” means we load your vehicle’s specific identification number and corresponding factory software onto the module before shipping it. This makes the unit plug-and-play, as it’s already configured for your truck’s exact options and systems, saving you a costly programming fee at a dealership.
Is this BCM difficult to install myself?
The physical installation is relatively simple for someone with basic mechanical skills. It’s usually located under the driver’s side dash and involves unplugging a few connectors and removing a few bolts. The most complex part can be the post-installation electronic procedures, like the airbag system sync, which may require a professional scan tool.
My airbag light is on after installing the new BCM. What should I do?
This is a common occurrence. The new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). You will need to have a qualified technician perform the “Setup SDM Primary Key in BCM” procedure using a compatible high-level scan tool to clear the light.
Will this part fit my 2010 Silverado if my original part number is different?
Yes, this BCM is compatible with a wide range of GM trucks and SUVs and interchanges with many different part numbers, including those found on a 2010 Silverado. We list many compatible part numbers on the product page, and our VIN programming ensures it will work correctly with your vehicle’s specific configuration.
