Restore Your Truck’s Electrical System with a VIN-Programmed BCM
If your 2010 Chevrolet Avalanche 1500 is suddenly plagued by a host of bizarre electrical issues, you’re not alone. As a technician with over two decades of experience, I’ve seen it all: power windows with a mind of their own, intermittent starting problems, dashboard lights flickering like a disco, and security system alerts for no reason. These aren’t separate problems; they’re classic symptoms of a failing Body Control Module (BCM). The BCM is the central computer for your truck’s comfort and convenience features, and when it goes, it can make your vehicle feel haunted.
This isn’t just an annoyance; a faulty BCM can impact safety systems. That’s why we offer a reliable, straightforward solution. This Body Control Module, part number 95151084, is the correct replacement for your truck. Better yet, we take the biggest headache out of the repair: programming. Simply provide your vehicle’s VIN at checkout, and our experts will program the module with the latest GM software specifically for your Avalanche. It arrives at your door ready for installation, saving you a trip to the dealership and hundreds in programming fees.
A Technician’s Notebook: The Avalanche with a Mind of Its Own
A customer brought in his 2010 Avalanche, completely frustrated. The radio would randomly shut off, the door locks would cycle while driving, and the “Service StabiliTrak” light was on. He’d already replaced the battery, thinking it was a simple voltage issue. My scan tool pulled multiple U-codes, indicating a communication breakdown between modules. After 20 years in the bay, this screamed BCM failure. We confirmed the diagnosis, installed one of our VIN-programmed modules, and performed the quick brake pedal position relearn. The electrical gremlins vanished instantly. The customer was relieved to have his reliable truck back without a massive dealership bill.
Is Your Avalanche Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need.
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ False warnings on the dashboard, such as “Service Airbag” or “Service StabiliTrak.”
- ✔ Communication error codes (U-codes) like U0140, U0155, or U0100 stored in the system.
- ✔ The radio or infotainment system malfunctioning or shutting down unexpectedly.
Your Straightforward BCM Installation Guide
Installing your new BCM is a manageable job for a confident DIYer. For the 2010 Avalanche, the BCM is typically located under the steering column. Always refer to a service manual for your specific vehicle’s procedure.
- Safety First: Disconnect the negative terminal from your truck’s battery and wait a few minutes for the system to fully discharge.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to access the module. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. Note their orientation. Then, unbolt or unclip the old BCM from its mounting bracket and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors firmly until they click into place.
- Perform Relearns: Reconnect the battery. You may need to perform a Brake Pedal Position Relearn or an Airbag System Sync as detailed in our post-install section. Test all functions (lights, windows, locks) to confirm the repair.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN during or after checkout, and it will arrive ready to install with the latest GM software for your specific vehicle.
What is a core charge? Do I need to send my old part back?
There is absolutely no core charge on this BCM. You can keep your old module, saving you the time and expense of a return shipment.
My airbag light is on after installation. Is the part defective?
No, this is a normal possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to sync the components and turn off the light.
Why do I need to do a Brake Pedal Position Relearn?
The BCM uses data from the brake pedal position sensor for functions like brake lights and the StabiliTrak/traction control system. A quick recalibration ensures this sensor communicates accurately with the new BCM, which is vital for safety.
Is this a difficult part to replace myself?
For someone with basic mechanical skills and tools, it’s a very manageable repair. The primary challenge is typically accessing the module under the dashboard. Since we handle the programming, the most complex part of the job is already done for you.
