Restore Full Functionality to Your GM Vehicle
Are you experiencing frustrating electrical problems in your GM car, truck, or van? Issues like erratic power windows, malfunctioning door locks, intermittent wipers, or a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and unpredictable symptoms. This replacement module is the definitive solution to get your vehicle back in perfect working order.
Why Choose Our Programmed GM Body Control Module?
Don’t waste time and money at the dealership. We offer a simple, direct solution. This isn’t just a part in a box; it’s a complete service. When you purchase from us, you provide your vehicle’s VIN, and we flash the module with the latest GM software specific to your car. This means it arrives at your door ready for installation, eliminating the need for expensive programming tools or a trip to a mechanic for post-install flashing. It’s the most efficient way to solve your BCM-related headaches.
Common Symptoms of a Failing GM BCM
- ✔ Power windows, mirrors, or seats not working or operating erratically.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The security system acting up, causing alarm or starting issues.
- ✔ Power door locks failing to engage or disengage.
- ✔ The instrument cluster displaying false warnings or gauges behaving strangely.
- ✔ A no-start condition where the engine cranks but won’t fire up.
- ✔ Communication error codes stored when checked with a diagnostic scanner.
Simple Installation Process
Once you receive your Programmed GM Body Control Module, the physical installation is typically straightforward. Locate your old BCM (often found in the dash or under the steering column), disconnect the battery, swap the modules, and reconnect everything. While the module is pre-programmed, some vehicles may require a simple relearn procedure for certain systems. For example, if your airbag light is on after install, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a Brake Pedal Position Relearn might be necessary for some models. Always consult a service manual for your specific vehicle for detailed instructions.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories not related to the engine, such as power windows, lights, security systems, door locks, and wipers.
How does the VIN programming work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We use this number to load the exact software and settings for your specific vehicle onto the BCM before we ship it to you.
Is this part difficult to install?
For someone with basic mechanical skills, the physical swap is generally not difficult. The BCM is usually located inside the cabin, under the dashboard. The main benefit of our service is that the complex software programming is already done for you.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This can happen on some models. It means the new BCM needs to be synchronized with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be done with a professional-grade diagnostic tool.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. If you are experiencing any of the symptoms listed, a failing BCM is a very likely cause. Proper diagnosis is always recommended to confirm the BCM is the point of failure.
