Are you battling bizarre electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or even a car that won’t start can all point to a single culprit: 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 create a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can be a major disruption to your daily life.
This listing is for a direct replacement BCM, professionally programmed to your vehicle’s specific VIN. We take the guesswork and expensive dealership trips out of the equation. Simply provide us with your VIN after purchase, and we’ll flash the module with the latest GM software updates, ensuring it’s ready for installation right out of the box. This restores the original functionality and communication between your vehicle’s electronic systems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Warning lights appearing on the dashboard for various systems (ABS, Airbag, Traction Control).
- ✔ Radio or climate control malfunctions.
Your Plug-and-Play GM Body Control Module Solution
Don’t let a faulty BCM keep your vehicle off the road. Our service provides a reliable and cost-effective solution. This module is a direct replacement for a wide range of original equipment part numbers, including 15093910, 25892622, 20815898, and many more as listed in the fitment data. By programming the module to your VIN, we ensure it integrates seamlessly with your vehicle’s existing systems, such as the engine computer, transmission module, and instrument cluster.
Installation Note: While this module is designed for plug-and-play installation, some vehicles may require additional steps after the new BCM is installed. If your airbag light illuminates, 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 proper brake light and traction control function. Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, mirrors, interior and exterior lighting, the security system, and even the windshield wipers.
Do I need to get this programmed at a dealership?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during checkout or in a message to us, and the module will arrive ready to install.
Is this a difficult part to replace?
The difficulty varies by model. The BCM is typically located under the dashboard on the driver’s or passenger’s side. Replacement usually involves removing a few trim panels and unplugging the electrical connectors. Most DIY mechanics with basic tools can perform the swap in under an hour.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Supplemental Inflatable Restraint (SIR) module. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade diagnostic tool.
Will this fix my specific problem?
If your vehicle’s issues match the common symptoms of BCM failure and your mechanic has diagnosed the BCM as the fault, this part is the correct solution. It’s crucial to ensure the BCM is the actual problem before ordering.
