Fix Your GM Truck’s Electrical Gremlins for Good
If you’re dealing with bizarre electrical issues in your 2007-2011 GMC Yukon—like flickering lights, a dead instrument cluster, or power windows with a mind of their own—you’ve likely met the frustrating reality of a failing Body Control Module (BCM). As the nerve center for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive a nightmare. This replacement module, a direct fit for part number 15878753, is the reliable, permanent solution you need. We pre-program it to your vehicle’s specific VIN, so it arrives ready for a simple, plug-and-play installation, getting you back on the road without a costly trip to the dealership.
A Technician’s Notebook: The Case of the Haunted Sierra
Just last month, a 2010 GMC Sierra rolled into my bay with a laundry list of complaints: the radio would cut out, the A/C blower was intermittent, and the security light would flash randomly, sometimes preventing the truck from starting. The owner had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a dozen communication codes pointing to the BCM. These GMT900 platform trucks are notorious for BCM failures, often due to internal solder joint cracks or water intrusion. By replacing the faulty unit with a VIN-programmed module like this one, we had all systems restored in under 30 minutes. It’s a common repair, and having a pre-programmed part is a massive time-saver.
Is Your Yukon Showing These Symptoms?
A failing BCM doesn’t always trigger a check engine light. Instead, watch for these common signs of trouble. If your vehicle is experiencing any of these, a new 2007-2011 Yukon BCM is the most likely fix.
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC system failures, such as the blower motor not working or temperature controls being stuck.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ An airbag warning light on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Intermittent stalling or misfires that seem unrelated to the engine itself.
- ✔ Communication errors with other modules on the vehicle’s network.
A Straightforward Guide to Installation
One of the best features of this module is its ease of installation. You don’t need to be a master mechanic to get this job done right in your own driveway. The entire process typically takes less than 15 minutes.
- Safety First: Always begin by disconnecting the negative terminal on 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 dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- Swap the Modules: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once unplugged, remove the old module from its mounting bracket and install the new one.
- Reconnect and Test: Plug the connectors firmly into your new BCM. Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, wipers, locks, windows, and HVAC to confirm the repair.
- Post-Installation Steps: In some cases, an “Airbag System Sync” or “Brake Pedal Position Relearn” may be required if you have warning lights after installation. This is done with a professional scan tool and ensures all systems communicate correctly.

Do I need to program this BCM?
Do I need to program this BCM?
No. We handle all the programming for you. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for plug-and-play installation, saving you a trip to the dealer.
Where is the BCM located on my 2008 GMC Yukon?
The Body Control Module is typically found under the driver’s side of the dashboard, near the steering column and fuse panel. It’s a black box with several large electrical connectors.
Will this replacement 2007-2011 Yukon BCM fix my airbag light?
It often does, as the BCM communicates with the airbag system (SDM). However, if the light remains on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to sync the modules.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any extra fees or hassle.
What should I do if some problems persist after installation?
While the BCM is a common failure point, persistent issues could indicate a problem elsewhere. From my experience, checking the main ground connections (especially the one near the BCM itself) is a critical next step. Poor grounds can mimic BCM failure.
