Restore Your Van’s Electrical Systems with a Plug-and-Play BCM
Is your Chevrolet Express Van plagued by frustrating electrical problems? Flickering lights, unresponsive power locks, a dead HVAC blower, or a persistent airbag light can bring your workday to a halt. These are classic signs of a failing Body Control Module (BCM). This replacement BCM, equivalent to part number 15136877, is the definitive solution. We pre-program it to your van’s specific VIN, ensuring it works right out of the box with no expensive dealership programming required. Get your workhorse back in reliable condition and eliminate those electrical gremlins for good.
Is Your Express Van Showing These Symptoms?
- ✔ Unreliable or non-functional power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, such as the blower motor not working or controls being unresponsive.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Erratic security system behavior or a no-start condition due to PassLock failure.
- ✔ Communication errors or a cluster of body-related DTCs that won’t clear.
Case Study: A Tricky Diagnosis
I had a 2006 Express 2500 work van in my bay that was driving the owner crazy. The dome lights would stay on, the power locks worked only half the time, and the battery would be dead every few days. The owner had already replaced the battery and alternator. After checking for parasitic draws, I traced the issue to the BCM. These modules are notorious for internal solder joint failures that create intermittent grounds, causing all sorts of unpredictable issues. Installing a VIN-programmed 2004-2007 Express 2500 BCM was the fix. The new module corrected the internal grounding path, and all the strange electrical issues vanished instantly. It’s a common failure point on these hard-working vans.
Plug-and-Play Installation: Get Back on the Road Fast
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts.
- ✔ Locate the BCM: On Express and Savana vans, the BCM is typically found in the center dash area, often accessible from below or by removing a lower dash panel.
- ✔ Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Remove any mounting bolts or clips holding it in place, then install the new module.
- ✔ Reconnect and Test: Re-attach the electrical connectors to the new BCM, ensuring they click securely into place. Reconnect the battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions: lights, locks, windows, wipers, and HVAC. In most cases, the repair is complete. For any lingering airbag lights, a ‘Setup SDM Primary Key’ procedure may be needed with a scan tool.

Frequently Asked Questions
Frequently Asked Questions
Do I need to program this BCM at the dealership?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you time and money on dealer fees.
What if the airbag light is still on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a mechanic with an advanced diagnostic scan tool.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any hassle or need to return it.
Will this fix my van not starting?
If the no-start is caused by the security system (PassLock) which is controlled by the BCM, then yes, this new module will resolve the issue. If the cause is something else (starter, fuel pump), it will not.
What is the warranty on this part?
This part comes with a one-year warranty, ensuring it provides reliable service for your vehicle.
Is this a genuine GM part?
This is a high-quality replacement part built to meet or exceed original equipment specifications for performance and reliability.
Why choose a VIN programmed 2004-2007 Express 2500 BCM?
Choosing a VIN programmed module ensures all the specific options your van was built with (like power locks, keyless entry, etc.) will function correctly without any additional setup. It’s the most reliable way to perform this repair.
