Is Your GM Truck or Van Plagued by Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2003-2007 GM truck or van, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lights and security system. When it starts to fail, it can create a cascade of confusing problems that are difficult to diagnose.
Is Your GM Truck or Van Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Intermittent warning lights on the dashboard, like the airbag or brake light.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Inaccurate gauge readings or gauges that stop working entirely.
A Reliable, Programmed Solution
Don’t let a faulty BCM keep your truck or van off the road. This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic functions. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN before we ship it. This ensures compatibility and simplifies the installation process, getting you back to a fully functional vehicle faster. This is a direct replacement for multiple part numbers, including 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689.
Important Post-Installation Information
After installing your new 2003-2007 Express BCM, some vehicles may require additional steps to ensure all systems communicate correctly. While this module is programmed for your VIN, the vehicle’s other computers may need to be re-introduced to the new BCM.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure your brake lights and traction control system function as intended.
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 controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and more. It’s the brain for your vehicle’s body electronics.
Is this part difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located under the steering column or in the center dash. Since we program it to your VIN, you avoid a trip to the dealer for programming, making it as close to plug-and-play as possible. However, some post-install relearn procedures may be necessary.
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 your BCM without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
What happens if the airbag light comes on after I install it?
This is a normal possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
