Is Your Work Van Plagued by Baffling Electrical Issues?
For a business owner or tradesperson, a Chevrolet Express 3500 isn’t just a vehicle—it’s a critical tool. When electrical gremlins strike, it means downtime, lost jobs, and immense frustration. If you’re dealing with flickering lights, malfunctioning power windows and locks, or a van that refuses to start, a failing Body Control Module (BCM) is often the culprit. This isn’t just an inconvenience; it’s a direct hit to your productivity. Stop chasing symptoms and get the definitive solution that gets you back on the road and back to work.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing problems that can be difficult to diagnose. You may be experiencing issues like power door locks activating on their own, interior lights staying on, security system errors, or communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or U0164. This pre-programmed Express 3500 Body Control Module is the reliable, cost-effective fix.

An Expert’s Note on Diagnostics: We’ve seen countless Express vans in the shop where owners have spent hundreds of dollars replacing batteries, alternators, and even starters, only to find the root cause was the BCM. A failing BCM can create phantom power drains that kill batteries overnight or send faulty signals that prevent the engine from cranking. By starting with the ‘brain’ of the system, this pre-programmed Express 3500 Body Control Module often solves multiple issues at once, saving you significant time and diagnostic headaches.
Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicle systems may require a recalibration procedure after the BCM is replaced. Please be aware of the following potential requirements:
- 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 professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is essentially the central computer for your van’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, the security system, and the instrument cluster. When it fails, it can cause a wide variety of strange electrical problems.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your exact van.
Will this fix my specific electrical problem?
This Express 3500 Body Control Module is the direct solution for a huge range of common electrical failures. If you’re experiencing multiple issues like erratic lights, door lock problems, and instrument cluster malfunctions, a faulty BCM is the most likely cause.
Do I need to send my original BCM back?
No. This product has no core charge. You can keep your original module, which simplifies the process and saves you the hassle and cost of return shipping.
What if my airbag light is on after I install it?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to your van’s airbag system (SDM). A qualified technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
