Restore Full Control of Your GM Truck or SUV
If you’re dealing with baffling electrical issues in your 2007-2011 GMC Yukon XL 1500—like flickering lights, an unresponsive climate control system, or power windows with a mind of their own—a failing Body Control Module (BCM) is the likely culprit. As a mechanic with over two decades of diagnostic experience, I’ve seen these modules cause some of the most frustrating and hard-to-trace problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and security. Our replacement BCM, a direct-fit for part number 15940214, is the definitive solution to get your vehicle’s electronics working in perfect harmony again.
Case Study: A Tricky Diagnosis
A customer brought in their ’08 Tahoe with a complaint that was all over the map: the radio would cut out, the A/C blower worked intermittently, and the security light would randomly flash, sometimes preventing the truck from starting. They had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a handful of communication loss codes (U-codes) pointing to the BCM. A quick check of the BCM’s ground connection under the dash—a notorious weak point on these platforms—confirmed it was secure. The module itself was failing internally. By installing a VIN-programmed 2007-2011 Yukon XL 1500 BCM, we solved all the ghost-like issues in one shot, saving the customer from endless diagnostic fees and the high cost of a dealership repair.
Is Your Yukon Exhibiting These Common BCM Failure Symptoms?
- ✔️ Power windows, door locks, or mirrors not working or behaving erratically.
- ✔️ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔️ HVAC and climate controls are unresponsive or the blower motor works intermittently.
- ✔️ The anti-theft or security system malfunctions, causing no-start conditions.
- ✔️ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔️ Unexplained battery drain when the vehicle is off.
- ✔️ Various communication DTCs stored in the system.
A Straightforward Guide to Your BCM Installation
One of the best features of this module is its simple, DIY-friendly installation. Since we program it to your vehicle’s VIN before shipping, you won’t need a trip to the dealer. The entire process takes less than 15 minutes for most owners.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Unbolt or unclip the old module and remove it.
- Install the New BCM: Secure the new module in the same position and plug all the connectors back in firmly. You’ll hear a click when they are properly seated.
- Reconnect and Test: Reconnect the negative battery terminal. Start your vehicle and test all the functions: lights, windows, locks, wipers, and HVAC to confirm the repair.
Post-Installation Note: In some cases, particularly if your old BCM was causing an airbag light, a post-install procedure may be needed. If the airbag light remains on, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” function. Similarly, a “Brake Pedal Position Relearn” might be necessary. These are simple procedures for any qualified shop. This pre-programmed 2007-2011 Yukon XL 1500 BCM resolves the hardware fault, making these final steps straightforward.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is the central computer for your vehicle’s body electronics. It doesn’t control the engine, but it manages almost everything else you interact with inside the cabin, like lights, power accessories, security, wipers, and climate control.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and options onto the module. This makes it a true plug-and-play part, ensuring all features work correctly without requiring expensive programming tools or a visit to a dealership.
Is this a difficult part for a DIYer to replace?
Not at all. The physical replacement is very simple, typically involving just a few connectors and bolts under the dashboard. Most home mechanics with basic tools can complete the job in under 15 minutes.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a common cause of the B1001 code. Replacing the module with this unit will fix the root cause. However, you may need a professional scan tool to perform the “SDM Key Setup” procedure to clear the light after installation.
What does ‘No Core Charge’ mean?
It means you don’t have to send your old, broken part back to us. This saves you the hassle and cost of return shipping and eliminates any core deposit, simplifying your purchase.
Is this module covered by a warranty?
Absolutely. This module is backed by our one-year warranty, giving you peace of mind and confidence in your repair.
