Are you battling frustrating electrical problems in your GM truck or van? Issues like malfunctioning power windows, erratic interior lights, or a persistent security warning on your dash often point to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, part number 15116065, is the definitive solution to restore full functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific VIN before shipping. This critical step ensures seamless integration with your truck’s existing systems, eliminating the need for expensive dealership programming. Simply provide your VIN, and we handle the rest, sending you a part that’s truly plug-and-play.
We had a 2005 Silverado 2500 in the shop where the owner had spent hundreds replacing a power window motor and a headlight switch, but the problems kept coming back intermittently. The radio would sometimes not turn off, and the dome light had a mind of its own. After hooking up the scan tool, we saw multiple communication loss codes pointing to a central failure. The culprit wasn’t the individual components; it was a failing BCM causing all the chaos. Installing a new, VIN-programmed BCM fixed every single issue in one go, saving the customer from further guesswork and expense.
Common Symptoms of a Failing GM BCM
- ✔ Power windows, door locks, or mirrors stop working or work intermittently.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on at all.
- ✔ The horn honks unexpectedly or doesn’t work.
- ✔ The anti-theft or security system acts up, preventing the vehicle from starting.
- ✔ Wipers operate erratically or not at all.
- ✔ The instrument cluster displays incorrect information or warning lights.
- ✔ Communication errors (U-codes) are present when scanned with a diagnostic tool.

Post-Installation Information
While this is a plug-and-play part, some vehicles may require minor post-installation procedures. If the airbag light appears, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure correct brake light and traction control operation. Always consult a factory service manual or a qualified technician if you are unsure about these steps.
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 various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these body-related functions.
Is this BCM truly plug-and-play?
Yes, for most vehicles. We program it to your VIN before shipping, which handles the main security and options programming. In some rare cases, minor relearn procedures for the airbag or brake pedal sensor may be needed, as detailed in the product description.
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 program and ship the module without it. Please double-check the VIN for accuracy to ensure correct programming.
What happens if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
Do I need to return my old BCM?
No. This product has no core charge, so you are not required to send your original module back to us.
