Is Your GM Truck or Van Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, unresponsive power windows and locks, or strange warning messages on your dash, 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 wide range of frustrating and unpredictable problems. Don’t let a faulty module compromise your vehicle’s reliability. This direct-replacement BCM is the definitive solution for restoring full electronic functionality to your truck or van.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system acting up or preventing the engine from starting.
- ✔ False warning lights on the instrument cluster (e.g., “Service 4WD”).
- ✔ Intermittent operation of the radio or climate controls.
- ✔ Complete loss of communication with the module, preventing diagnostics.

Post-Installation Steps
While this module is delivered ready for installation, some vehicles may require one or two simple relearn procedures after the BCM is installed. These are standard procedures when replacing this component.
- 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” function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Note: No core charge! You can keep your original module.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and climate controls.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. For example, if your power locks, interior lights, and radio all act up intermittently, the BCM is a primary suspect. A diagnostic scan showing communication errors with the BCM is a definitive sign.
What is the process after I place my order?
After you purchase, you will need to provide us with your vehicle’s 17-digit VIN. We use this to program the module with the correct software and vehicle-specific options before we ship it to you.
Is this part difficult to install?
For most GM trucks and vans, the BCM is located under the steering column or in the center dash area. It’s typically held in by a few bolts or clips and has several electrical connectors. Basic mechanical skill is sufficient for the physical replacement.
Do I need a mechanic to perform the post-installation procedures?
While the physical installation is DIY-friendly, procedures like the Airbag System Sync require a professional-grade bidirectional scan tool. If the airbag light appears, a visit to a qualified technician will be necessary to complete the process.
