Restore Your Truck’s Electrical System and Get Back to Work
Is your truck or van plagued by strange electrical problems? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or an intermittent no-start condition can sideline your vehicle and disrupt your work. These frustrating issues often point to a single culprit: a failing Body Control Module (BCM). This isn’t just an annoyance; for a work vehicle, it’s a critical failure that costs you time and money. Stop chasing electrical gremlins and install a reliable, permanent solution.

Expert Insight: Don’t Replace the Wrong Part
From over 20 years of diagnostic experience, I’ve seen countless technicians and DIYers waste money replacing perfectly good components like starters, alternators, and batteries when the BCM was the real issue. A failing BCM can send incorrect signals, making other parts seem faulty. For example, a BCM that doesn’t recognize the key’s security chip will prevent the starter from engaging, looking exactly like a bad starter. By correctly diagnosing the issue and installing a properly programmed 2003-2007 Express 3500 BCM, you’re not just fixing the symptom; you’re solving the root cause efficiently.
Installation & Post-Install Notes
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the steering column in pickups or in the center dash area on vans. After installation, please be aware that some vehicles may require one or two simple relearn procedures. If the airbag light is on, a “Setup SDM Primary Key in BCM” procedure may be needed. In some cases, a “Brake Pedal Position Relearn” might also be required. These procedures can be performed by most professional repair shops with a capable scan tool.
Getting your truck back to full operational status is our top priority. This programmed 2003-2007 Express 3500 BCM is the most dependable and efficient way to do it.
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. This includes power windows, locks, interior/exterior lighting, the security system, and more.
How do I know if my BCM is the problem?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. For example, if your dome light won’t turn off and your power windows stop working simultaneously, the BCM is a very likely culprit.
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 truck’s specific options, such as power windows, keyless entry, and security system. This ensures a true plug-and-play installation.
Is this BCM difficult to install?
For most experienced DIYers or any professional technician, the installation is simple. It involves locating the old module, disconnecting the battery, swapping the electrical connectors to the new module, and mounting it in place. The key is that our pre-programming saves you the most complex step.
What if my airbag light is on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a high-level scan tool can perform the “Setup SDM Primary Key in BCM” procedure to sync the modules and turn off the light.
Does this part replace other part numbers?
Yes, this BCM is a direct replacement for a range of part numbers, including 15167329, 15194169, 15136224, 15116065, 15198115, 15136876, and 10367689. If your original module has one of these numbers, this is the correct part for you.
