Is your 2003-2006 Chevrolet Suburban 2500 suffering from bizarre electrical issues? A faulty Body Control Module (BCM) is often the culprit behind problems like flickering lights, malfunctioning power windows, a dead instrument cluster, or even a no-start condition. The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a wide range of frustrating symptoms. This OEM-quality replacement BCM, part number 10383536, is the definitive solution to restore your vehicle’s full functionality.
To eliminate the hassle and expense of a dealership visit, we pre-program this module to your vehicle’s specific VIN. This ensures it arrives ready for a true plug-and-play installation. Simply provide your VIN at checkout, and our technicians will flash the module with the latest GM software, making it a seamless replacement for your original part.
We had a 2005 Suburban 2500 come in that was a complete electrical nightmare. The owner reported the radio would turn on by itself, the door locks would cycle randomly while driving, and the HVAC blower was completely unresponsive. After checking all the usual suspects like fuses and grounds, we hooked up our scanner and found multiple communication loss codes with the BCM. Instead of a lengthy and expensive diagnostic process at the dealer, we installed one of our VIN-programmed modules. The installation took less than 10 minutes, and upon reconnecting the battery, every single issue was resolved. The customer was back on the road the same day, saving hundreds in labor and programming fees.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes it ready for installation right out of the box, with no additional programming required.
What tools are needed for installation?
Installation is simple and typically requires only basic hand tools, such as a socket set or screwdriver, to access the module under the dashboard. The entire process usually takes less than 15 minutes.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade scan tool. This is only necessary if the airbag light appears after the swap.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, which saves you the time and money associated with return shipping.
