Is Your GM Van or SUV Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a vehicle that refuses to start, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let electrical gremlins keep your vehicle off the road. This replacement BCM is the reliable, straightforward solution you need.
From the Diagnostic Bay
We had a 2011 Express work van come in that was driving the owner crazy. The radio would turn on and off by itself, the dome lights would stay on, and occasionally the van wouldn’t start, only to fire right up an hour later. The owner had already replaced the battery and checked the alternator. After running diagnostics, we traced the communication errors back to a faulty BCM. Once we installed a VIN-programmed replacement, all the strange electrical issues vanished instantly. It was like giving the van a brand new nervous system.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic behavior from the dashboard gauges or warning lights (including the security light).
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ Problems with the keyless entry or factory alarm system.
- ✔ A/C and heater controls not responding correctly.
- ✔ Communication issues that can lead to a no-start condition.

Important Post-Installation Notes: While this module is programmed for your vehicle, certain security and safety systems may require a relearn procedure after installation. This is a standard part of the repair process for many modern vehicles. You may need a professional scan tool to perform a “Setup SDM Primary Key in BCM” if the airbag light is on, or a “Brake Pedal Position Relearn” for proper brake system function. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and climate controls.
Is this module ready to install when I receive it?
Yes, it comes pre-programmed to the VIN you provide, making it ready for physical installation. However, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal position sensor, which may require a professional scan tool.
How do I provide my VIN?
You can add your 17-digit VIN in the notes section at checkout or send it to us in a message after you complete your purchase. We cannot ship the module until we have your VIN.
What if the airbag light is on after I install the BCM?
This is a common occurrence. A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade diagnostic tool to sync the new BCM with your vehicle’s airbag system.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
