Fix Your Yukon’s Electrical Problems for Good
If your 2007-2011 GMC Yukon is suffering from baffling electrical issues—like the A/C cutting out, power windows refusing to work, or a persistent airbag light—you’ve likely met the culprit: a failing Body Control Module (BCM). As the nerve center for your vehicle’s comfort and convenience features, a faulty BCM can cause a cascade of frustrating problems. This replacement module, a direct-fit for part number 15901388, arrives fully programmed to your vehicle’s VIN. This means you can skip the expensive trip to the dealership for programming; it’s a true plug-and-play solution designed to restore full functionality right out of the box.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2009 Yukon that came into my bay with a laundry list of complaints from the owner. The radio would randomly shut off, the driver’s side window worked only when it wanted to, and the security light would flash, occasionally preventing the truck from starting. The owner had already replaced the battery and checked the main grounds. After hooking up my scanner, I saw a dozen communication codes pointing to the BCM. These modules are notorious for internal circuit board failures over time. We installed a VIN-programmed BCM, and within 10 minutes, every single issue was resolved. It’s a common failure, and this part is the definitive fix.
Is Your Yukon Exhibiting These Telltale Signs?
A failing BCM doesn’t always trigger a check engine light. Instead, watch for these common symptoms that indicate it’s time for a replacement. Addressing them with a new 2007-2011 Yukon BCM can prevent further electrical complications.
- ✔ The air conditioning or heater blower motor works intermittently or not at all.
- ✔ Your airbag warning light is on, often with a DTC B1001 (Setup SDM Primary Key in BCM) stored.
- ✔ Power windows, door locks, or interior/exterior lights operate erratically or have stopped working completely.
- ✔ The anti-theft or security system malfunctions, causing no-start conditions or false alarms.
- ✔ Unexplained battery drain occurs overnight, even with everything turned off.
- ✔ Multiple communication-related Diagnostic Trouble Codes (DTCs) are present.
Your 5-Minute Path to a Fully Functional Yukon
For most DIYers, this is a quick and straightforward repair. You don’t need specialized tools, and the entire process can be completed in less time than it takes to drink a cup of coffee. Just follow these simple steps.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On your Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a small black box with several large electrical connectors.
- Swap the Module: Carefully unplug the wiring harness connectors from the old BCM. They have locking tabs that need to be depressed. Unbolt or unclip the old module and set it aside.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the wiring connectors. You’ll hear a click as they lock into place.
- Power Up: Reconnect the negative battery terminal. Start your vehicle and test all functions—windows, locks, lights, and HVAC—to confirm the repair was successful.
Post-Installation Note: In some cases, particularly if you had an airbag code, a ‘Setup SDM Primary Key’ or ‘Brake Pedal Position Relearn’ procedure may be needed. This requires a bi-directional scan tool and ensures the new BCM communicates perfectly with all other vehicle systems. There is no core charge, so you can keep your old part.

Frequently Asked Questions
Frequently Asked Questions
What does a ‘VIN-Programmed’ BCM mean for me?
It means the module arrives ready for installation. We flash it with your vehicle’s specific VIN and the latest GM software, so it works seamlessly with your existing keys and options without needing a dealership to program it.
Do I need to take my truck to a dealer after installing this?
No. Because the module is pre-programmed to your VIN, you avoid the costly programming fees and hassle of a dealership visit. It’s designed to be a direct, ready-to-install solution.
My airbag light is on. Will this fix it?
This module will often resolve the underlying electronic fault causing an airbag light (like DTC B1001). However, after installation, you may need a mechanic with a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this a difficult part to replace myself?
For most people with basic tools, this is a very easy repair. The BCM is typically accessible under the dashboard, and the replacement involves simply swapping a few electrical connectors. The entire job usually takes less than 15 minutes.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the repair process for you.
