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, the Body Control Module (BCM) is very often the component to blame. As a technician with over two decades of experience, I’ve seen these modules cause some of the most frustrating problems—from flickering lights and a malfunctioning radio to a vehicle that won’t start. This isn’t just an inconvenience; it’s a matter of reliability. This OEM-quality Body Control Module, equivalent to part number 15926094, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.

The BCM is the central command center for your vehicle’s body electronics. It manages everything you interact with daily: your power windows, door locks, climate control, interior and exterior lighting, and even the security system. When it fails, it can create a cascade of seemingly unrelated symptoms. Our module arrives expertly pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership programming. This makes for a true plug-and-play repair, getting your Yukon XL 1500 BCM back to factory-spec performance quickly and affordably.

Is Your Yukon XL Showing These Electrical Glitches?

A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need. Don’t let these issues go unchecked, as they can worsen over time.

• ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
• ✔ HVAC (climate control) blower motor staying on, or controls being unresponsive.
• ✔ The security system acting erratically, preventing the vehicle from starting.
• ✔ Interior dome lights or exterior lights (headlights, taillights) not working correctly.
• ✔ An airbag warning light on the dash, often accompanied by DTC B1001.
• ✔ Seemingly random warning lights and messages appearing on the instrument cluster.

A Straightforward Guide to Installation

One of the best features of this module is how simple the installation is. For most DIYers or professional mechanics, the entire process takes less than 10 minutes. Here’s a simple breakdown of the steps:

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
2. Locate the Module: The BCM is typically located under the driver’s side dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
3. Remove the Old Unit: Carefully disconnect all electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
4. Install the New Module: Mount your new, pre-programmed Yukon XL 1500 BCM in the same location and securely re-attach all electrical connectors. You should hear a ‘click’ as they lock into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, windows, locks, HVAC, etc.—to confirm the repair was successful.

Post-Installation Note: In some cases, particularly if you had an airbag light, a ‘Setup SDM Primary Key’ procedure may be needed using a professional scan tool. This re-syncs the new BCM with the airbag system. A brake pedal position relearn might also be required for certain models.
