Is Your GM Vehicle Experiencing Strange Electrical Problems?
If your car’s lights are flickering, windows and locks are acting erratically, or you’re seeing random warning lights on your dash, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. Don’t let electrical gremlins take over your vehicle. This direct-fit replacement BCM is the reliable solution to restore your car’s proper function.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Malfunctioning windshield wipers and washers.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ False warning lights, such as the airbag or ABS light, appearing on the dash.
- ✔ Problems with the heating and A/C controls.
Why Choose Our Programmed GM Body Control Module?
This isn’t just a part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair process. Before we ship your order, our technicians will program the module with the latest GM software updates using your vehicle’s specific Vehicle Identification Number (VIN). This ensures that the BCM communicates perfectly with your vehicle’s other systems right out of the box, eliminating the need for a costly trip to the dealership for programming.
Please provide your VIN in the notes at checkout or send us a message after your purchase to prevent any shipping delays.
Post-Installation Information
While our programming handles the critical setup, some vehicles may require minor additional steps after installation. These are known as relearn procedures and can sometimes be necessary to sync all systems.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper function of the brake lights and traction control system.
Frequently Asked Questions
What does a Body Control Module (BCM) 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, locks, lights, wipers, security systems, and climate controls.
Is this BCM ready to install when I receive it?
Yes! We pre-program this GM Body Control Module to your vehicle’s VIN before shipping. This ensures it works with your specific options and systems, making installation much simpler than a non-programmed module.
How do I provide my VIN number?
You can add your 17-digit VIN to the order notes during checkout or send it to us in a message immediately after placing your order. We cannot ship the part until we have your VIN for programming.
What if my airbag light comes on after I install the BCM?
This is not uncommon. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep your original module.
