A failing BCM is the central cause of many frustrating electrical gremlins. If your Express van is experiencing any of the following, this module is your fix:
- Intermittent or non-working power windows, door locks, or interior/exterior lights.
- HVAC controls that are unresponsive or a blower motor that works sporadically.
- An airbag warning light that won’t turn off, often accompanied by DTCs like B1001.
- Security system malfunctions, including no-start conditions where the engine won’t crank.
- A cluster of seemingly unrelated diagnostic trouble codes pointing to body system failures.

Expert Insight: The Real Cost of a Bad BCM
We once had a plumbing contractor with an Express 3500 whose van wouldn’t start every other morning. He’d already replaced the battery and starter. The issue was a failing BCM causing a security system fault. The dealership quoted him a two-day wait time plus programming fees. That’s two days of cancelled jobs and lost revenue. We sent him a VIN-programmed BCM overnight. He installed it himself in the parking lot in under 10 minutes the next morning and was back on the road to his first job. For a work vehicle, a fast, pre-programmed solution isn’t a convenienceโit’s a business necessity.
Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your van’s other electronic systems right out of the box, with no need for a trip to the dealer for additional programming.
Why is my airbag light still on after installation?
In some cases, the new BCM needs to be electronically introduced to the airbag system’s computer (the SDM). This is a security feature. A procedure called “Setup SDM Primary Key in BCM” can be performed with a professional-grade scan tool to sync the modules and turn off the light.
Do I have to send my old part back?
No. There is no core charge or requirement to return your original module. You can keep it or dispose of it at your convenience, making the repair process simpler and faster.
Where is the BCM located on my Express 3500?
On the 2004-2007 Express and Savana vans, the Body Control Module is typically located in the center of the dashboard, accessible after removing some of the dash trim panels. Always disconnect the battery before starting the replacement.
Will this fix my specific electrical problem?
This Programmed 2004-2007 Express 3500 Body Control Module is the correct solution for the wide range of symptoms listed above. As the central hub for body electronics, a faulty BCM is the most common cause of these issues in this vehicle platform.
