Tired of Unpredictable Electrical Problems in Your GM Truck?
As a technician with over two decades of experience, I’ve seen it all when it comes to vehicle electronics. One of the most common sources of frustrating, hard-to-diagnose issues in 2007-2011 GM trucks and SUVs is a failing Body Control Module (BCM). This module is the central command for your vehicle’s comfort and convenience features. When it starts to fail, it can feel like your truck has a mind of its own. This replacement 2007-2011 GM Body Control Module, part number 15263497, is the definitive solution to restore order and reliability.
We take the guesswork and hassle out of the repair by programming the module to your vehicle’s specific VIN before it ships. This means no expensive trips to the dealership for programming—it arrives ready for a straightforward, plug-and-play installation. Get your power windows, door locks, climate control, and security system working flawlessly again.
Case Study: A Tricky Diagnosis
I remember a 2009 Silverado 2500 that came into my shop with a laundry list of complaints: the radio would cut out, the driver’s side window worked intermittently, and the airbag light was on with a DTC B1001. The owner had already replaced the battery and checked fuses. After confirming the grounds were solid, we hooked up the scanner and saw multiple communication errors pointing toward the BCM. Instead of a costly diagnostic path, we installed a VIN-programmed BCM. In less than 10 minutes, the strange electrical behavior was gone. A quick SDM key sync with our scanner cleared the airbag light, and the truck was back on the road, fully functional. This is a classic BCM failure scenario.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, there’s a strong chance this module is the cause:
- ✔ The HVAC blower motor is dead or works only on certain speeds.
- ✔ Power windows, door locks, or interior lights operate erratically or not at all.
- ✔ The security system acts up, causing no-start or stalling conditions.
- ✔ An airbag warning light is illuminated, often with a B1001 code.
- ✔ You’re chasing persistent grounding issues or communication DTCs (U-codes).
- ✔ Wipers or exterior lights function incorrectly.
A Straightforward Guide to Installation
One of the best parts about this solution is its simplicity. You can have your truck’s electronics restored in minutes right in your own driveway.
- Safety First: Always disconnect the negative battery terminal before working on vehicle electronics.
- Locate the BCM: On most compatible GM models, you’ll find the BCM located under the driver’s side dash, near the steering column.
- Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unclip or unbolt the old module from its bracket.
- Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely reconnect all electrical connectors. You’ll hear a click as they lock into place.
- Reconnect & Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
Post-Installation Note: In some cases, particularly if you had an airbag light on, you may need to perform a “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. A Brake Pedal Position Relearn may also be required on certain models. And remember, there is no core charge, so you don’t have to worry about sending the old part back.

Frequently Asked Questions
Does this BCM really not require dealership programming?
That’s correct. We program the module to the VIN you provide during checkout. It arrives ready to be installed, saving you time and money on dealer service fees.
How difficult is the installation for a DIYer?
The physical replacement is very simple and typically takes less than 15 minutes with basic hand tools. It’s located under the dash and involves unplugging the old unit and plugging in the new one.
What if my airbag light stays on after installation?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s Sensing and Diagnostic Module (SDM). This procedure, called “Setup SDM Primary Key in BCM,” must be done with a bi-directional scan tool and resolves the light.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep or dispose of your old module without any hassle.
Will this fix a no-start condition?
It can. The BCM is tied into the vehicle’s anti-theft and security system. If the BCM is the root cause of the security fault, replacing it can resolve starting issues.
