Restore Full Electrical Function to Your GM Truck
Are you battling frustrating and unpredictable electrical problems in your truck? Issues like power windows that won’t cooperate, door locks with a mind of their own, a security light that won’t turn off, or interior lights that flicker can make your reliable workhorse feel untrustworthy.

An Expert’s Insight: Why Programming is Non-Negotiable
As a technician, I’ve seen countless truck owners try to save a few dollars by installing a used BCM from a salvage yard. It never works. The BCM is the electronic gatekeeper for your vehicle’s specific features, from the type of radio it has to whether it has power seats. This information is coded directly to the original vehicle’s VIN. Installing an unprogrammed or incorrectly programmed module is like giving your truck a brain transplant with the wrong memories—it leads to chaos, features that don’t work, and a vehicle that may not even start. Our service takes that gamble completely off the table. By programming the 1999-2000 Silverado 2500 BCM specifically for your truck before it even ships, we ensure it integrates seamlessly, restoring function correctly the first time.
Frequently Asked Questions
What information do you need to program the BCM?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your truck. This allows us to flash the module with the exact software and configuration your vehicle requires.
Is this part difficult to install?
The physical installation is straightforward for a DIYer with basic tools. The BCM is typically located under the driver’s side or center of the dashboard. Because we pre-program the unit, the most difficult part of the job is already done for you. However, please review the potential post-installation procedures, as some vehicles may require a simple relearn process for certain systems.
Do I need to send my old BCM back to you?
No. This product has no core charge. You can keep your original part, which saves you the hassle and expense of return shipping.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be electronically introduced to the airbag system. If the airbag light appears, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the modules and resolves the light.
My original part number is slightly different. Will this work?
Yes, this module is a direct replacement for a range of part numbers, including 19153625, 8191536250, 16257125, and more. As long as your vehicle’s year, make, and model are on our compatibility list, this programmed 1999-2000 Silverado 2500 BCM is the correct part for the job.
