Is Your Van Plagued by Electrical Gremlins?
Are you dealing with frustrating and unpredictable electrical issues in your Chevy Express or GMC Savana? One moment the power locks work, the next they don’t. The interior lights have a mind of their own, or your dashboard is lit up with strange warning messages. These aren’t isolated incidents; they’re classic symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of baffling problems that are difficult to diagnose.
Common Symptoms of a Failing BCM:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system acting up, causing no-start conditions or a “Service Theft System” message.
- ✔ Horn honking randomly or failing to work when needed.
- ✔ Windshield wipers activating intermittently without input.
- ✔ Instrument cluster gauges behaving strangely or providing incorrect readings.
- ✔ False warning lights appearing on the dashboard.
- ✔ Communication error codes (U-codes) stored when scanned.
From the Diagnostic Bay
We had a 2014 Express 2500 work van come into the shop that was driving the owner crazy. His main complaint was a dead battery every few mornings. He’d already replaced the battery and the alternator, but the problem persisted. On top of that, his power door locks would only work sometimes. After checking for a parasitic draw, we traced it to the BCM, which wasn’t letting the vehicle’s networks go to ‘sleep’ properly. It was also causing the intermittent lock failure. Instead of a costly trip to the dealer for a new module and programming fees, we installed a VIN-programmed unit just like this one. The van was back in service the next day, problem-free. It saved the owner hundreds in parts, labor, and downtime.
The Plug-and-Play Solution: A Pre-Programmed Express 1500 BCM
Don’t let a faulty module keep your vehicle off the road. This Body Control Module is the definitive solution to restore your vehicle’s electronic functions. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific 17-digit VIN before it ships. This means it arrives ready for installation, loaded with the latest software updates from GM. You get a part that is precisely matched to your vehicle’s options and systems, eliminating the need for expensive dealership programming.
Installation and System Resets
Physically installing the BCM is a straightforward process for a knowledgeable DIYer or any professional technician. It is typically located in the center dash area on Express and Savana vans. Once installed, the module will communicate with your vehicle’s other systems. However, in some cases, minor post-installation procedures may be required.
- 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-grade scan tool. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper function of the brake lights and stability control systems.
We make the process even easier with our No Core Charge policy. You don’t have to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.

Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest GM software for your specific model and options, then flash it directly onto the BCM. This ensures it works correctly with your vehicle right out of the box.
Is this part truly ‘plug-and-play’?
For most vehicles, yes. Because it’s programmed to your VIN, it eliminates the need for dealer-level programming to get the vehicle started and running. However, as noted in the description, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor, which can be done with a professional scan tool.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, saving you time and money.
Where is the BCM located on my 2013 Express Van?
On the 2013-2014 Express and Savana vans, the Body Control Module is typically found in the center of the dashboard, often accessible by removing lower dash panels. For other compatible vehicles, the location may vary. We always recommend consulting a factory service manual for precise location and removal instructions.
Will this fix my exact problem?
This module will resolve any issue directly caused by a faulty BCM. The symptoms we’ve listed are the most common indicators of BCM failure. However, to be 100% certain, we always advise having a proper diagnosis performed by a qualified mechanic to rule out other potential causes like wiring or sensor issues before placing an order.
