Is your GM truck or SUV plagued by strange electrical issues?
If you’re dealing with flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that won’t start, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 15095334, is the definitive solution for restoring full functionality to your vehicle.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ Unexplained battery drain that leaves you with a dead battery.

Installation & Post-Install Information
Installation is typically straightforward, as the BCM is located in the center dash area on models like the Blazer, Jimmy, S10, and Astro, or under the steering column on full-size trucks like the Silverado and Sierra. While our programming handles the majority of the setup, some vehicles may require additional steps after the new BCM is installed.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be necessary to ensure brake lights and traction control function correctly.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and instrument panel gauges.
What happens after I order this part?
After you complete your purchase, you will need to provide us with your 17-digit VIN. Our technicians will then program the BCM with the correct software for your vehicle’s options before we ship it to you.
Is this part difficult to install?
For someone with moderate DIY mechanical skill, the replacement is manageable. The BCM is usually located in the center dash or under the steering column. The main benefit of our service is that the complex programming is already done for you.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Will this BCM fit vehicles other than a Blazer or Jimmy?
Yes, this BCM is compatible with a wide range of 2002-2005 GM trucks and vans, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Astro, and Safari. Please check the fitment list to confirm it matches your specific vehicle and options.
Will this fix my airbag light?
If the BCM was the cause of the airbag light, this replacement may resolve it. However, after installation, the system may require an ‘Airbag System Sync’ procedure with a professional scan tool to turn off the light.
