Are you battling frustrating electrical gremlins in your truck? Flickering lights, unresponsive power windows, a dead HVAC system, or a security light that won’t turn off are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing issues. This OEM-quality BCM, part number 10383536, is the definitive solution for your 2003-2006 Chevrolet Avalanche, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
- ✔ 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 functioning or blower motor issues.
- ✔ Airbag warning light illuminated on the dash, often with a B1001 DTC.
- ✔ Vehicle security system malfunctions, leading to no-start conditions.
- ✔ Intermittent electrical functions that seem to have no logical cause.
Why Choose Our 2003-2006 Avalanche BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the complex programming so you don’t have to. By programming the module to your specific VIN before shipping, we ensure it communicates flawlessly with your truck’s other systems right out of the box. This eliminates the need for expensive trips to the dealership for calibration. Built to strict OEM standards, this module restores the reliability and functionality you expect from your vehicle.
Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the steering column. Simply disconnect the vehicle’s battery, unplug the connectors from your old module, remove it, and install the new one. Reconnect the battery, and you’re done. In most cases, the process takes less than 10 minutes.
Post-Installation Procedures: While the module is plug-and-play, some vehicles may require a ‘re-learning’ procedure. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. In some cases, a Brake Pedal Position Sensor relearn may also be necessary. These are simple procedures for any qualified technician.
Frequently Asked Questions
Is this BCM ready to install right out of the box?
Yes! We pre-program the module to your vehicle’s specific VIN before shipping. This ensures it’s ready for a plug-and-play installation without requiring a trip to the dealership for programming.
Where is the BCM located on my 2004 Avalanche?
On the 2003-2006 Chevrolet Avalanche and similar GM trucks like the Silverado and Tahoe, the Body Control Module is located under the driver’s side of the dashboard, near the steering column.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synced with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your old module without any hassle or extra fees.
Will this part fix a no-start problem?
It can. The BCM is a critical part of the vehicle’s anti-theft and security system (Passlock/VATS). If the BCM has failed, it can prevent the engine from starting. Replacing it often resolves these security-related no-start conditions.
This part number 10383536 is different from my original. Will it work?
Yes. GM often updates part numbers. This module is a direct replacement and is interchangeable with many part numbers, including 15116066, 15136225, 15198116, and others listed in the description.
