Restore Your Vehicle’s Electrical System with Confidence
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that refuses to start can all point to 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 confusing and unpredictable problems. This Programmed GM Body Control Module 15880684 is the definitive, hassle-free solution to restore order and get your truck, van, or SUV operating exactly as it should.
Common Symptoms & Your Solution
A faulty BCM can be difficult to diagnose, often mimicking other issues. If you’re experiencing any of the following, a failing module is the likely culprit:
- Interior or exterior lights staying on or not working at all
- Power windows, door locks, or mirrors operating erratically or not at all
- The security system light is on, or the alarm goes off randomly
- Instrument cluster gauges behaving strangely or displaying warning lights
- Intermittent no-start or no-crank conditions
- Diagnostic Trouble Codes (DTCs), especially U-codes, indicating a loss of communication
Instead of paying for expensive dealership diagnostics and programming fees, this module arrives at your door programmed specifically for your vehicle. We use your VIN to flash the unit with the latest, most stable software updates from GM, ensuring a seamless installation and reliable, long-term performance. This is the most direct path to fixing those electrical issues for good.

Expert Insight: Why Pre-Programming is Non-Negotiable
From over 20 years of hands-on diagnostics, I can tell you that installing a non-programmed BCM is a recipe for frustration. A BCM from a salvage yard might look identical, but it’s coded to the donor vehicle’s options and security system. Installing it will, at best, result in features not working, and at worst, prevent your vehicle from starting altogether. Our VIN-specific programming service isn’t just a convenienceโit’s the critical step that makes this a viable, effective repair for the serious DIYer or independent shop. We ensure the digital “handshake” between the BCM and your vehicle’s other computers happens flawlessly.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic functions not related to the engine. This includes power windows, locks, interior and exterior lighting, security systems, wipers, and more.
Is this module truly “plug and play”?
Yes, because we program it to your vehicle’s VIN before shipping, it is ready for installation. In some rare cases, certain models may require a simple relearn procedure for the airbag system or brake pedal position sensor, which is detailed in the product information. However, the core programming that allows the vehicle to run and operate is complete.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for the programming process.
What if my airbag light comes on after installation?
If the airbag light illuminates, it simply means the new BCM needs to be synced with the airbag’s computer (SDM). This is resolved by performing a “Setup SDM Primary Key in BCM” procedure with a professional-grade scan tool. This is a common and straightforward step for a qualified technician.
Do I need to return my old BCM?
No. This product has no core charge. You can keep, recycle, or dispose of your original module at your convenience.
How do I know my BCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis often requires a professional scan tool to check for communication codes (U-codes) from the BCM. If you have multiple, unrelated electrical issues happening at once, the BCM is the most common point of failure.
