Is Your GM Truck or SUV Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, a malfunctioning climate control system, or power windows with a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and difficult-to-diagnose issues. This is especially common in hardworking trucks and SUVs like the Chevrolet Tahoe, Silverado, Suburban, and their GMC counterparts. Instead of paying for expensive dealership diagnostics and programming, get the simple, effective solution right here.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or wipers.
- ✔ HVAC system acting erratically, with a blower motor that won’t turn on or off, or incorrect temperature control.
- ✔ An airbag warning light illuminated on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system faults that cause no-start conditions, random stalling, or prevent the key fob from working.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Strange lighting behavior, such as interior or exterior lights staying on or not working at all.

This OEM-quality Body Control Module is the definitive fix for these issues. We take the hassle out of the replacement process by pre-programming the module to your vehicle’s specific VIN. This means no extra trips to the dealer and no expensive programming fees. It arrives at your door ready for a plug-and-play installation. By using the latest GM software updates during programming, we ensure optimal performance and communication between all your vehicle’s electronic systems. This replacement for part 15901388 (and others like 25844480, 25971916, 20939137) restores the precise control you expect from your vehicle.
Installation is straightforward for any DIYer with basic tools. The BCM is typically located under the driver’s side dashboard, near the steering column. In most cases, the process takes less than 15 minutes. While the module is plug-and-play, some vehicles may require a simple post-installation procedure. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new module with the airbag system. This is a quick procedure for any qualified technician.
Frequently Asked Questions
Is this BCM really plug-and-play?
Yes, it comes pre-programmed to your vehicle’s VIN for a straightforward installation. In some cases, a post-install procedure like an airbag system sync may be required, which needs a professional scan tool.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing it with our programmed module should resolve the issue, but you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the light after installation.
