End Frustrating Electrical Problems in Your GM Truck or SUV
Are you dealing with bizarre electrical issues in your Silverado, Sierra, Tahoe, or Yukon? One moment the power windows work, the next they don’t. The A/C blower cuts out randomly, or dashboard warning lights appear for no reason.

Expert Insight: The ‘Programmed is Prepared’ Advantage
Many owners are tempted to buy a used BCM from a salvage yard to save a few dollars. However, that’s a gamble. A used module is programmed to a different vehicle and will not communicate correctly with your truck’s specific systems, like the ECU, instrument cluster, and anti-theft system. This leads to more errors, more frustration, and ultimately a trip to the dealer for programming that often costs more than this part. Our VIN-programmed 25835965 Body Control Module arrives ready to work, saving you critical time, money, and the headache of a failed repair.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine-related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Is this module difficult to install?
Installation is typically straightforward for those with basic mechanical skills. The BCM is usually located under the driver’s side dashboard near the steering column and can often be replaced in under 15 minutes with simple hand tools.
Will I need to take my truck to the dealership after installation?
No. Because we pre-program the module to your vehicle’s VIN, you can skip the dealership visit. It’s designed to be a plug-and-play solution right out of the box.
How do I know if my BCM is the problem?
If you are experiencing multiple, seemingly unrelated electrical issues such as failing lights, erratic locks, and intermittent HVAC control, it is a strong indicator of a faulty BCM. A professional scan tool can also confirm the diagnosis by revealing communication-related DTCs.
What if the airbag light stays on after I install the new BCM?
In some cases, especially if DTC B1001 was present, a final sync procedure is needed. A professional scan tool with special functions is required to perform the ‘Setup SDM Primary Key in BCM’ command to sync the airbag system with the new module.
Do I need to return my old part?
No, there is no core charge for this part. You can keep or dispose of your old module at your convenience.
