Experiencing Frustrating Electrical Issues in Your GMC Yukon XL?
If your 2007-2011 GMC Yukon XL 1500 is plagued by unpredictable electrical problems—like flickering lights, malfunctioning power windows and locks, or a climate control system with a mind of its own—a failing Body Control Module (BCM) is the most likely culprit. This critical component acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can make driving stressful and unsafe. Restore the dependable performance you rely on with this direct-fit, VIN-programmed BCM.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, disrupting your vehicle’s comfort and safety systems. This module is the definitive solution if you’re experiencing:
- Unresponsive or intermittent HVAC and blower motor controls.
- An illuminated airbag warning light, often accompanied by DTC B1001.
- Power windows, door locks, or interior/exterior lights that work sporadically or not at all.
- Malfunctions with the security system, causing starting issues or unexpected stalling.
- A variety of diagnostic trouble codes (DTCs) related to body functions.

Expert Insight: Check Your Grounds
From over 20 years of hands-on diagnostics, I can tell you that a solid ground connection is non-negotiable for any BCM. The GMT900 platform (which your Yukon is built on) is known for potential grounding issues, especially at the main ground point under the driver’s door on the frame. Before installing your new Yukon XL 1500 Body Control Module 25835966, take 10 minutes to inspect and clean this ground. A poor ground can cause voltage spikes and communication errors that mimic a bad BCM, and failing to address it can damage your new part. A clean, tight connection is the best insurance for a successful repair.
Frequently Asked Questions
What does a Body Control Module do on a Yukon XL?
The BCM is a computer that manages and controls many of your SUV’s non-engine related electronic systems. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and the HVAC climate control system.
Is this BCM difficult to install?
No, the physical installation is straightforward for most people with basic tools. The BCM is typically located under the driver’s side dashboard near the steering column. The entire process often takes less than 15 minutes. Since it comes pre-programmed, no special computer is needed for the initial setup.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and configurations onto the BCM. This ensures it communicates correctly with all other modules in your Yukon, like the engine computer and airbag system. Without it, many features will not work correctly, and you would have to pay a dealership to program it.
Will this fix my airbag light with a B1001 code?
Yes, this is a common symptom of BCM failure. After installing the new module, if the airbag light remains on, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a compatible high-level scan tool. This syncs the new BCM with the airbag system.
Do I need 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 or hassle, making the replacement process even simpler.
How do I know if this is the right part for my vehicle?
The best way to ensure compatibility is to match the part number from your original module to one of the numbers listed in our description.
