Restore Full Functionality to Your GM Truck or SUV
If you’re dealing with a frustrating array of electrical issues in your 2007-2011 GMC Yukon, you’re not alone. Seemingly random problems like a dead instrument cluster, flickering lights, or a non-responsive HVAC system often point to one central culprit: a failing Body Control Module (BCM). As the electronic nerve center for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive a nightmare. This replacement BCM, part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play fix that gets you back on the road without a costly trip to the dealership.
Case Study: A Tricky Diagnosis
I recently had a 2009 Silverado 2500 in the shop with a classic ghost-in-the-machine problem. The owner complained of intermittent power window failure, a radio that would shut off randomly, and the security light staying on, preventing the truck from starting. My initial check pointed to a possible grounding issue, as these symptoms were all over the place. After cleaning and testing the main body grounds with no improvement, I hooked up my professional scanner. It revealed a slew of U-codes (communication errors) pointing back to the BCM. This is a textbook example of how a failing 2007-2011 Yukon BCM (and its counterparts in other GM trucks) can mimic other problems. Installing a VIN-programmed module resolved every single issue instantly.
Is Your Truck Showing These Symptoms?
- ✔ The air conditioning or heater blower motor works intermittently or not at all.
- ✔ Your power windows, door locks, or interior lights have stopped working or behave erratically.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Setup SDM Primary Key Mismatch).
- ✔ The security system malfunctions, causing no-start conditions, stalling, or misfires.
- ✔ Your dashboard is lit up with multiple warning lights without a clear cause.
- ✔ Diagnostic scans show communication errors (U-codes) or other body-related fault codes.
A Straightforward Guide to Installation
Getting your truck back to normal is easier than you think. This installation typically takes less than 10 minutes and requires basic hand tools. No complex wiring or dealer visits are necessary.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- 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 locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start your vehicle and test all functions—windows, locks, wipers, lights, and HVAC—to confirm the repair was successful.
Post-Installation Note: In some cases, particularly if you had an airbag light on, the system may require a ‘Setup SDM Primary Key’ procedure. This is not a full programming but a simple sync function that can be done with most professional-grade scan tools. A brake pedal position relearn may also be needed for some models to ensure proper brake light and stability control function.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Do I need to program this module at a dealership?
No. We pre-program this BCM to your vehicle’s specific VIN before shipping. This ensures it works correctly right out of the box, saving you the time and expense of a dealer visit.
My airbag light is on. Will this fix it?
A faulty BCM can cause the airbag light to come on with code B1001. Replacing the BCM is the correct fix, but you may need to perform an ‘SDM Key Sync’ with a professional scan tool after installation to turn off the light. This is a simple sync procedure, not full programming.
Is this part difficult for a DIYer to install?
Not at all. The BCM is typically held in place by a few clips or bolts under the dashboard and has several plug-in connectors. With basic tools, most people can swap it out in under 10 minutes.
What does ‘No Core Charge’ mean?
It means you don’t have to send your old, faulty BCM back to us. This saves you the hassle and cost of return shipping and eliminates any core deposit fees.
