Are you experiencing frustrating and unpredictable electrical problems with your 2008-2012 Buick Enclave? Issues like flickering lights, malfunctioning power windows or locks, or a security system that acts up on its own are often signs of 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 confusing symptoms. This is a direct-fit replacement Body Control Module, part number 20935349, that solves these issues without a trip to the dealership for expensive programming.
From the Diagnostic Bay
We had a 2011 GMC Acadia (which shares the same platform as the Enclave) come into the shop with a list of bizarre electrical complaints. The radio would turn off randomly, the liftgate wouldn’t open with the remote, and the dome lights had a mind of their own. The customer had already replaced the battery, but the problems persisted. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a complicated and costly dealer visit, we installed a VIN-programmed module just like this one. The installation was straightforward, and all the strange electrical gremlins were gone instantly. It’s a fix that restores the vehicle’s functionality and the owner’s peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Unexplained battery drain leading to a dead battery.
- ✔ Vehicle failing to start, even with a good battery and starter.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure full functionality. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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 relearn may be necessary to ensure your brake lights and traction control system function as intended.

Frequently Asked Questions
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 to you. It arrives ready for installation, saving you hundreds in dealership fees.
What does the Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine related electronic features, such as power windows, locks, lights, wipers, security system, and instrument cluster functions.
Where is the BCM located on a 2008-2012 Buick Enclave?
On the 2008-2012 Enclave, the BCM is typically located behind the dashboard on the driver’s side (LH dash).
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A qualified technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module.
