Is your Saturn Outlook or other GM vehicle suffering from strange and unpredictable electrical problems? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of frustrating issues, from flickering lights to a complete no-start condition. This replacement Body Control Module, part number 20864767, is the reliable, cost-effective solution to restore full functionality to your car, truck, or van.
From the Diagnostic Bay
We had a 2009 GMC Acadia come into the shop with a list of complaints that seemed completely unrelated. The radio would turn off randomly, the driver’s side power window worked intermittently, and the anti-theft light would flash, sometimes preventing the car from starting. The owner had already replaced the battery to no avail. A full diagnostic scan showed multiple communication loss codes with various modules. This pointed us directly to the BCM. After installing a VIN-programmed module like this one, every single electrical gremlin was gone. It’s a perfect example of how one failing component can make a vehicle seem like it’s falling apart.
Unlike a standard replacement, this BCM is delivered to you pre-programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. This critical service saves you a trip to the dealership and hundreds of dollars in programming fees, making the repair process faster and more straightforward. Simply provide your VIN at checkout, and we handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior lighting.
- ✔ The security or anti-theft system light is on, or the vehicle won’t start.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Wipers activating on their own or not responding.
- ✔ Communication error codes (U-codes) stored in the system.
- ✔ Malfunctions with the radio, HVAC, or climate control systems.

Installation Notes
While the module arrives programmed, some vehicles may require simple post-installation relearn procedures. These can often be performed with a high-end scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the installation process.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and more.
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it. This makes it ready for installation right out of the box, saving you time and money.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag module (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a difficult part to replace?
The difficulty varies by model. The BCM is typically located under the dashboard on the driver’s or passenger’s side. While it’s a plug-in component, accessing it may require removing some interior trim panels.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module.
