Restore Full Electrical Control to Your GM Vehicle
Are you experiencing baffling electrical issues in your Chevrolet Express Van, Silverado, or GMC Sierra? Intermittent power windows, a malfunctioning security system, or unpredictable HVAC controls are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating problems. This OEM-quality Body Control Module, equivalent to part number 15136225, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2006 Silverado 2500 in the shop that was driving the owner crazy. The radio would turn on by itself, the dome light would flicker, and the power locks worked only when they wanted to. The owner had already replaced the battery and checked all the fuses. After connecting our scanner, we saw a handful of communication error codes pointing to the BCM. Instead of a complex wiring nightmare, the fix was simple: a new, VIN-programmed Body Control Module. Once installed, all the strange electrical gremlins vanished instantly. It’s a classic case where one central component causes multiple, seemingly unrelated symptoms.
Is Your BCM Failing? Common Symptoms
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ HVAC and climate control systems not working or blowing air intermittently.
- ✔ An illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system malfunctions, leading to no-start conditions.
- ✔ Non-functional windshield wipers or washers.
- ✔ A variety of communication-related DTCs stored in the vehicle’s memory.
The Power of VIN Programming for Your Express 1500 Body Control Module
Forget about expensive trips to the dealership for programming. We handle the critical step for you. Before shipping, we program this module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that the BCM communicates flawlessly with your vehicle’s other electronic modules right out of the box. It arrives ready for a plug-and-play installation, loaded with the latest GM software updates to ensure optimal performance and reliability. This process eliminates compatibility issues and saves you hundreds in dealer service fees.
Installation and Post-Install Considerations
Installation is straightforward for DIYers and professionals alike. The BCM is typically located under the steering column or behind the center dash panel. Disconnecting the battery before swapping the module is recommended. While our VIN programming handles the primary setup, some vehicles may require a simple relearn procedure after installation. If your airbag light remains on, a technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Best of all, there is no core charge, so you can keep your old part without any hassle.
This module is a direct replacement for a wide range of part numbers, including: 10383536, 15116066, 15136225, 15136877, 15137393, 15137394, 15137395, 15137396, 15198116, 15257043, 15257044, 15257045, 15257046, 10367690, 15064149, and 15194170.
Frequently Asked Questions
What does a Body Control Module do on my Express Van?
The BCM is a computer that manages and controls many of your van’s non-engine related electronic features. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC blower motor functions.
Is this Express 1500 Body Control Module difficult to install?
No, the physical installation is typically very simple, often taking less than 15 minutes. It involves unplugging the electrical connectors from the old module and plugging them into the new one. The module is usually found under the driver’s side dashboard.
Why is VIN programming so important for a BCM?
VIN programming loads your vehicle’s specific configuration and security information onto the module. Without it, the BCM won’t recognize your vehicle, leading to a no-start condition or malfunctioning features. Our pre-programming service makes it a true plug-and-play part.
Will I need to go to the dealer after installing this part?
In most cases, no. Our VIN programming eliminates the need for dealer setup. However, on some models, if the airbag light stays on, a scan tool procedure to sync the airbag system (SDM) may be required. This can be done by most professional repair shops.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems, potential security system lockouts that prevent the vehicle from starting, and even battery drain if a component is being kept active. It can make your vehicle unreliable and unsafe.
