Restore Full Functionality to Your GM Truck or SUV
Are you battling frustrating electrical issues in your Chevy S10, Silverado, GMC Sierra, or Blazer? Flickering lights, malfunctioning power windows, or a security system with a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable problems. This replacement Body Control Module is the definitive, hassle-free solution to restore your vehicle’s electronic systems to perfect working order.
Unlike a standard used part from a junkyard, this module is meticulously tested for full functionality and then programmed specifically to your vehicle using your 17-digit VIN. We install the latest available software updates from GM, ensuring optimal performance and reliability that often exceeds the original factory unit. This plug-and-play solution eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
From the Diagnostic Bay
We had a 1999 GMC Jimmy come into the shop with a classic “electrical gremlin” case. The customer complained of the radio turning off randomly, the dome light refusing to shut off—draining the battery overnight—and the power locks working only intermittently. They had already replaced the battery and checked fuses to no avail. A quick scan showed communication errors with the BCM. Instead of a costly diagnostic and programming session at the dealer, we installed one of our pre-programmed modules. In under an hour, every single issue was resolved. The customer was thrilled to have their truck back to normal without the dealership headache.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the most likely culprit. This replacement S10 Body Control Module is designed to correct these exact issues:
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on at all)
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all
- ✔ Vehicle security system issues, such as the alarm randomly activating or the ‘Security’ light staying illuminated
- ✔ Horn not working or sounding unexpectedly
- ✔ Windshield wipers behaving erratically (wrong speeds, not parking correctly)
- ✔ Instrument panel gauges giving incorrect readings or not working
- ✔ Climate control or radio malfunctions
- ✔ A persistent parasitic battery drain that you can’t trace to another source
Plug-and-Play Installation Process
This BCM is designed for a straightforward installation. On models like the S10, Blazer, and Jimmy, it is typically located behind the center of the dashboard. On trucks like the Silverado and Sierra, it’s often found on the driver’s side, behind the lower dash panel. Once you locate and swap the module, most functions will be immediately restored. However, please be aware of a few potential post-installation steps:
- Airbag System Sync: In some vehicles, the airbag warning light may illuminate after installation. This is a normal security measure. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on certain models to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages non-engine related functions. This includes power windows, locks, interior/exterior lights, the security system, wipers, and more.
Do I need to get this BCM programmed by a dealer?
No! We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you a trip to the dealership and their expensive programming fees.
How do I provide my VIN?
After you complete your purchase, you will receive an order confirmation email. Simply reply to that email with your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program and ship your part.
What if my original part number isn’t on the list?
The part numbers listed, especially ID 16257125, cover a wide range of original parts that are interchangeable. As long as your vehicle’s year, make, and model are on our compatibility list, this module will work once programmed to your specific VIN.
Why is the airbag light on after installation?
This is a normal security feature. The new BCM needs to be electronically synced with the airbag system’s computer (SDM). A professional scan tool is used to perform a quick ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
