Is Your GM Truck or Van Acting Possessed?
Are you dealing with flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or random warning lights on your dash? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to go, it can cause a cascade of frustrating and unpredictable problems. Driving a vehicle with these issues isn’t just irritating—it can be unsafe.
The Simple, Reliable Solution: A VIN-Programmed BCM
Forget expensive diagnostic fees and programming charges at the dealership. We offer a direct-fit replacement BCM that arrives at your door completely programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load it with the latest GM-certified software, ensuring all your truck or van’s original features work seamlessly from the moment you plug it in. This is the most efficient way to restore full functionality and peace of mind.
Expert Pro Tip: Check for Water Intrusion First
In my 20+ years in the shop, I’ve seen hundreds of BCM failures on these GM trucks and vans. Before you replace the module, take a flashlight and inspect the area around it, especially the A-pillar and firewall. A common cause of failure is a leaking windshield seal or a clogged cowl drain that allows water to drip directly onto the BCM’s connectors, causing corrosion and short circuits. Fixing the leak is just as important as replacing the part to prevent the new module from failing prematurely.
Symptoms of a Failing GM BCM:
- ✔ Erratic or non-functional power windows and door locks
- ✔ Interior or exterior lights staying on or not working at all
- ✔ Horn honking randomly or not working
- ✔ The security or anti-theft system preventing the vehicle from starting
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’)
- ✔ Intermittent A/C or blower motor operation
Easy Installation for a Confident Repair
This Programmed GM BCM is designed for a straightforward installation. Since we handle the programming, you can perform the replacement yourself with basic tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the BCM: On Silverado and Sierra pickups, it’s typically found under the steering column. On Express and Savana vans, it’s located in the center of the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt or unclip the old BCM and remove it.
- Install the New BCM: Mount the new module in place and securely reconnect all electrical connectors.
- Reconnect Battery: Reattach the negative battery terminal.
CRITICAL: Post-Installation Procedures Required
After installing your new Programmed GM BCM, a couple of final steps are necessary to ensure all vehicle systems are synchronized and operating safely. These procedures require a professional-grade diagnostic scan tool.
- Airbag System Reset: The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure to re-establish communication between the BCM and the airbag system. This is a critical safety step.
- Brake Pedal Position Sensor Relearn: Some vehicles may require a recalibration of the brake pedal position sensor. This ensures the brake lights and stability control systems function correctly.
If you are not comfortable performing these procedures, we strongly advise seeking assistance from a qualified automotive technician.
