Restore Your GM Vehicle’s Electrical System
Are you battling persistent electrical gremlins in your 2004-2007 Chevrolet Express 2500 Van? Issues like erratic power windows, a non-responsive HVAC system, or mysterious warning lights are often traced back to a failing Body Control Module (BCM). The BCM acts as the central command for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of frustrating problems. This OEM-quality replacement BCM, part number 15136877, is the definitive solution to restore your vehicle’s functionality and peace of mind.
Symptoms of a Failing Express 2500 Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Intermittent or non-working interior and exterior lights.
- ✔ Power door locks or windows operating erratically or not at all.
- ✔ HVAC blower motor or climate controls failing to respond.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Security system malfunctions, leading to a no-start condition.
- ✔ Inconsistent windshield wiper operation.
- ✔ Communication errors with other vehicle modules.
The Plug-and-Play Advantage: Pre-Programmed to Your VIN
Forget the hassle and expense of dealership programming. We program this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it integrates seamlessly with your existing systems right out of the box. The module arrives ready for a straightforward, plug-and-play installation, restoring all factory settings and functions without any additional calibration for most vehicles. This module is a direct replacement for a wide range of part numbers, including 15116066, 15136225, 15198116, and more, guaranteeing a perfect fit for your Chevrolet Express, GMC Savana, Silverado, Sierra, or other compatible GM model.
Installation and Post-Install Notes
Installation is simple for the DIY mechanic. In most Express and Savana vans, the BCM is located in the center of the dash. For trucks and SUVs, it’s typically found under the steering column. The process usually takes less than 15 minutes. While our VIN programming handles the primary setup, some vehicles may require a simple relearn procedure if an airbag light appears. If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the systems. There is no core charge, so you can keep your old part without any extra cost or hassle.
