Common Symptoms of a Failing 2003-2007 GM BCM
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The horn honks unexpectedly or doesn’t work.
- ✔ The vehicle’s security system acts up, causing a no-start condition or a constant security light.
- ✔ Wipers or the radio function intermittently.
- ✔ The instrument cluster displays incorrect information or warning lights.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss (U-codes) are present.
Installation and Post-Install Requirements
Installation is straightforward for most DIY mechanics. On Silverado and Sierra pickups, the BCM is typically located under the steering column. On Express and Savana vans, it’s found in the center of the dash. While our VIN programming makes this a near plug-and-play repair, some vehicles may require simple post-installation relearn procedures to ensure all systems are properly synced.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to satisfy the traction control system.
This replacement 2003-2007 GM BCM is your reliable, cost-effective solution to restore your vehicle’s electronic systems to perfect working order. No core charge is required, so you can keep your original module.
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 a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, the security system, and the radio.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and features. This ensures the module works correctly right out of the box.
Is this BCM difficult to install?
For most models, the BCM is located under the driver’s side dashboard and is accessible with basic hand tools. The physical replacement is typically a simple process of disconnecting the battery, unplugging the electrical connectors, and swapping the module.
Will I need to take my truck to the dealer after installation?
No. Because we pre-program the module to your VIN, you will not need a trip to the dealer for programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems, which can be done with a professional-grade scan tool.
What happens if I don’t perform the relearn procedures if needed?
If your vehicle triggers a warning light after installation, failing to perform the required relearn can result in a persistent airbag light or improper brake light function. It’s important to perform these steps to ensure all safety systems are operating as intended.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without any additional fees.
