Restore Full Electrical Function to Your Chevy Express Van
Are you experiencing frustrating electrical problems in your 2004-2007 Chevrolet Express 1500 Van? Issues like flickering lights, unresponsive power locks, erratic HVAC controls, or even a no-start condition are often traced back to a failing Body Control Module (BCM). This essential component acts as the central hub for your van’s body electronics. When it fails, it can cause a cascade of confusing and disruptive symptoms. This OEM-quality replacement BCM, part number 15137395, is the definitive solution to restore your vehicle’s reliability and functionality.
Diagnosing a Faulty Express 1500 BCM
A failing BCM can manifest in numerous ways, often mimicking other component failures. If your Express Van is showing any of the following signs, a faulty BCM is the likely culprit. This module is the key to resolving these persistent electrical gremlins for good.
- ✔ Unresponsive or intermittently working power windows, door locks, or interior lights.
- ✔ HVAC system malfunctions, such as the blower motor not working or temperature controls being inoperative.
- ✔ The security system acting up, leading to false alarms or preventing the engine from starting.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble codes (DTCs) like B1001.
- ✔ Non-functional windshield wipers or washers.
- ✔ Communication errors between various vehicle modules, leading to a host of DTCs.
The Advantage of a VIN-Programmed Module
Don’t settle for a generic module that requires expensive and time-consuming trips to the dealership for programming. We pre-program this BCM to your van’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it arrives ready for a true plug-and-play installation. The module will have the latest GM software updates and will be perfectly configured for your vehicle’s options, resolving common DTCs and ensuring optimal performance right out of the box.
Installation and Post-Install Considerations
Installation is straightforward. The BCM is typically located in the center dash area on the Express Van. Once you’ve swapped the module, most functions will be immediately restored. However, in some cases, minor follow-up procedures may be needed:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
This part requires no core charge, so you can keep your old module without any hassle or extra cost.
