Restore Control and Reliability to Your GM Truck or Van
If you’re dealing with a frustrating array of electrical gremlins in your Silverado, Sierra, Express, or Savana, a failing Body Control Module (BCM) is often the culprit. As a technician with over two decades of experience, I’ve seen these issues countless times: power windows with a mind of their own, interior lights that won’t turn off, a security system that randomly immobilizes the engine, or dashboard warning lights that flicker for no reason. These aren’t just annoyances; they can compromise your vehicle’s safety and leave you stranded. Don’t let a faulty BCM dictate when and where you can drive.
This is your direct-fit, reliable solution. We take the guesswork and high dealership costs out of the equation. This genuine OEM-spec BCM, part number 15194169, is professionally programmed to your vehicle’s specific VIN before it ships. This means no expensive trips to the dealer for programming. It arrives ready for installation, loaded with the latest GM software updates to ensure peak performance and compatibility. By providing us with your VIN at checkout, you get a component that is truly tailored to your truck or van, restoring the precise electronic functions it had from the factory.
From the Diagnostic Bay
A customer brought in his 2006 Silverado 2500 last month with a classic BCM failure story. The dome lights would stay on, draining the battery overnight, and the power door locks worked intermittently. He’d already replaced the battery and checked fuses, but the problems persisted. After a quick scan, we saw multiple communication codes pointing to the BCM. The original module had visible corrosion on one of the main connectors from a minor windshield leak he never knew he had. We installed one of our pre-programmed BCMs, and within an hour, every single electrical issue was resolved. He drove away with a reliable truck and saved hundreds compared to the dealership’s quote.
Is Your GM Truck or Van Showing These Signs?
A failing BCM can cause a wide range of symptoms. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic power windows, door locks, or mirrors
- ✔ Interior or exterior lights staying on or not working at all
- ✔ The security or anti-theft system preventing the vehicle from starting
- ✔ Inaccurate or non-functional gauges on the instrument cluster
- ✔ False warning lights (e.g., ‘Service 4WD’, ‘ABS’, ‘Airbag’)
- ✔ Horn sounding unexpectedly or not working
- ✔ Problems with the heating and A/C blower motor controls
Your Straightforward BCM Installation Guide
Installing your new 2003-2007 GM BCM is a manageable job for a DIYer with basic tools. Follow these steps carefully.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow the system to fully discharge.
- Locate the BCM: On Silverado and Sierra pickups, the BCM is typically located under the driver’s side of the dashboard, near the steering column. For Express and Savana vans, it’s usually found behind the center dash panel.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Take note of their colors and positions.
- Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and remove it. Install the new, pre-programmed BCM in its place.
- Reconnect Everything: Plug the electrical connectors firmly into the new BCM. Reconnect the negative battery terminal.
- Perform Post-Install Procedures: After installation, you must perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the airbag light. Some vehicles may also require a brake pedal position sensor recalibration. If you are unsure, consult a professional.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the BCM to the VIN you provide before shipping. This eliminates the need for expensive scan tools or a trip to the dealership for programming.
Where do I provide my VIN?
Please enter your 17-digit Vehicle Identification Number (VIN) during the checkout process or send it to us in a message immediately after your purchase.
Will this fix my ‘Service Airbag’ light?
Replacing the BCM will illuminate the airbag light. You must have a technician perform the ‘Setup SDM Primary Key in BCM’ procedure with a bi-directional scan tool to sync the BCM with the airbag module and turn off the light.
