Is Your GM Truck or SUV Plagued by Baffling Electrical Issues?
If you’re dealing with flickering lights, a malfunctioning HVAC system, or power accessories that have a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This OEM-quality replacement BCM, part number 10383536, is the definitive solution for a wide range of 2002-2007 GM vehicles, including the Cadillac Escalade, Chevrolet Silverado, GMC Sierra, and more.
Is Your GM Vehicle Showing These BCM Failure Symptoms?
- ✔ Intermittent or non-functional HVAC controls and blower motor.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ An active security system light, leading to no-start or key recognition problems.
- ✔ The airbag warning light is illuminated, often with DTC B1001.
- ✔ A variety of seemingly random diagnostic trouble codes (DTCs) related to body systems.

Installation and Post-Install Notes
Installation is simple for the average DIYer and typically takes less than 15 minutes. The BCM is usually located under the driver’s side dashboard, near the steering column. Always disconnect the battery before swapping the modules. In most cases, no further steps are needed. However, if your airbag light remains on, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. There is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It controls non-engine related functions like power windows, locks, interior/exterior lights, wipers, the security system, and the HVAC system.
Is this BCM really plug-and-play?
Yes. We program the module to your vehicle’s VIN before it ships. This means you can simply install it without needing a trip to the dealership for programming, saving you time and money.
What if the airbag light is on after I install it?
If the airbag light appears, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a common step and does not indicate a faulty part.
Do I need to send my old BCM back?
No. There is no core charge or return requirement for this part. You can keep or dispose of your old module as you see fit.
Where is the BCM located on my 2004 Silverado?
On most GM trucks and SUVs from this era, including the Silverado, Tahoe, and Escalade, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
Will this fix my intermittent ‘Service 4WD’ message?
While the BCM can cause a wide range of electrical issues, a ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM) or the encoder motor. It’s best to diagnose the specific trouble codes before ordering a BCM for that issue.
