Frequently Asked Questions
What does a Body Control Module do on a Silverado or Sierra?
The BCM acts as the main computer for your truck’s body-related accessories. It controls power windows, locks, lights, the security system, wipers, and HVAC functions. When it fails, these systems can become erratic or stop working altogether.
Is this BCM really plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck’s other computers, so you can simply install it without needing a trip to the dealer for programming.
My airbag light is on after installing the new BCM. What do I do?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed with a professional-grade diagnostic scan tool.
How do I know for sure my BCM is bad?
Common signs include multiple, unrelated electrical issues happening at once (e.g., windows and radio fail together), security light flashing, and specific BCM-related trouble codes. If you’re experiencing several of the symptoms listed, the BCM is the most likely cause.
Do I need to return my old BCM?
No. This part has no core charge, so you can keep your original module without any extra fees or hassle.
Will this fit my 2005 Tahoe if my original part number is different?
Yes, this module is a direct replacement for many part numbers, including 10383536, 15136225, 15137393, 15198116, and others. As long as your vehicle is listed in the compatibility chart, this part will fit and function correctly.
