Restore Full Electrical Function to Your GM Vehicle
Are you experiencing frustrating electrical problems in your Chevrolet Express Van, Silverado, or GMC Sierra? Issues like malfunctioning power windows, erratic door locks, a dead HVAC system, or a persistent airbag light are often caused by a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of confusing and disruptive problems. This OEM-quality replacement BCM, part number 10367690, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2006 Express 3500 work van come into the shop with a classic case of BCM failure. The owner reported the dome lights wouldn’t turn off, the power locks worked intermittently, and the A/C blower was completely dead. After confirming power and ground to the BCM, we scanned for codes and found a slew of communication errors. Instead of a costly trip to the dealer, the owner opted for one of our VIN-programmed modules. The installation took less than 10 minutes, and upon reconnecting the battery, the lights, locks, and A/C all came back to life immediately. It’s a straightforward fix that solves a complex-seeming set of problems.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or intermittently working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ HVAC and climate control systems not functioning correctly (e.g., blower motor won’t run).
- ✔ Vehicle security system malfunctions, including no-start or key fob recognition issues.
- ✔ Illuminated airbag warning light, often accompanied by diagnostic trouble codes like B1001.
- ✔ Wipers operating erratically or not at all.

Installation and Post-Install Notes
The BCM is typically located in the center dash on Express and Savana vans. While the physical swap is fast, some vehicles may require a post-installation procedure. If your airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. In some cases, a Brake Pedal Position relearn may also be necessary. Always consult a factory service manual for your specific model if you are unsure.
Frequently Asked Questions
What does this Body Control Module do?
The BCM controls many of your vehicle’s non-engine related electronic accessories, such as power windows, locks, interior and exterior lighting, wipers, the security system, and the HVAC blower motor.
Is this BCM ready to install when I receive it?
Yes! This module is fully pre-programmed to your vehicle’s VIN before shipping. This makes it a plug-and-play solution that does not require a trip to the dealership for additional programming.

On the Express and Savana vans, the BCM is typically found behind the center dash area. On most trucks and SUVs, it is located under the steering column.
What if the airbag light is on after I install the new BCM?
If the airbag light is on, the vehicle needs a simple procedure called “Setup SDM Primary Key in BCM” performed with a professional-grade scan tool to sync the new BCM with the airbag system.

No, there is no core charge for this part. You can keep or dispose of your old module without any extra fees or hassle.
