Tired of Your Truck’s Mind of Its Own?
Is your Chevrolet Suburban, Silverado, or GMC Sierra suffering from a case of electrical chaos? One minute the air conditioning works, the next it doesn’t.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is the central computer for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows, door locks, security system, wipers, and climate control system.
Is this BCM truly “plug and play”?
Yes. Because we program it to your vehicle’s specific VIN number before shipping, it is ready to be installed without any additional dealer programming. It’s designed for a simple, direct installation.
What if my airbag light stays on after installation?
In some cases, especially if you had an airbag code like B1001, a post-install procedure called “Setup SDM Primary Key in BCM” may be required. This is a simple sync that can be performed with a professional-grade scan tool and ensures the new BCM communicates correctly with the airbag system.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping a return.
How do I know for sure that my BCM is the problem?
While only a full diagnostic can be 100% certain, a failing BCM is the most common cause of multiple, seemingly unrelated electrical issues like the ones listed above. If your lights, locks, and windows are all acting up at once, the BCM is the primary suspect.
Where is the BCM located on my vehicle?
On most compatible GM trucks and SUVs from this era, the BCM is located under the driver’s side dashboard, near the steering column. Installation typically takes less than 15 minutes.
