Restore Full Electrical Function to Your GMC Savana Van
Are you battling persistent electrical gremlins in your 2004-2007 GMC Savana 3500? A faulty Body Control Module (BCM) is often the culprit behind a frustrating array of issues, from non-responsive power windows and door locks to erratic HVAC behavior and mysterious warning lights. This genuine OEM-quality BCM, part number 15194170, is the definitive solution. It serves as the central nervous system for your van’s body electronics, and we deliver it pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
Diagnosing a Failing 2004-2007 Savana BCM
The Body Control Module manages a wide range of comfort, convenience, and security features. When it begins to fail, the symptoms can be confusing and seem unrelated. This module is the key to resolving those problems and getting your van back to reliable working order.
Common Symptoms of BCM Failure
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) flicker, stay on, or won’t turn on.
- ✔ The HVAC system is unresponsive, or the blower motor works erratically.
- ✔ Your vehicle’s security system malfunctions, leading to false alarms or a no-start condition.
- ✔ The airbag warning light is illuminated, potentially with DTC B1001 stored in the system.
- ✔ Wipers behave unpredictably, either not working or not parking in the correct position.
Plug-and-Play Solution with VIN Programming
Forget about expensive dealership visits and additional programming fees. We program this module with the latest GM software updates using your van’s VIN before it ships. This ensures that all factory-installed options are recognized and function correctly as soon as you plug it in. The process is simple:
- Locate your current BCM, typically found in the center dash area on Savana vans.
- Disconnect the vehicle’s battery.
- Carefully unplug the electrical connectors from the old module and remove it.
- Install the new module and reconnect the connectors.
- Reconnect the battery.
In most cases, the installation is complete. However, for some vehicles, a couple of simple post-installation procedures may be needed. If the airbag light remains on, a ‘Setup SDM Primary Key in BCM’ procedure may be required using a professional scan tool. Similarly, a Brake Pedal Position Relearn might be necessary for certain models. There is no core charge, so you can keep your old part without any hassle.
This module is a direct replacement and interchanges with a variety of part numbers, including 15116066, 15136225, 10383536, 15198116, and 15194170. Restore your van’s reliability and functionality today.
Frequently Asked Questions
What does the Body Control Module (BCM) do on my Savana Van?
The BCM is a computer that controls and monitors most of your van’s non-engine related electronic systems. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this part difficult to install myself?
No, installation is very straightforward for someone with basic mechanical skills. It’s a plug-and-play part located in the center dash. The entire process typically takes less than 15 minutes. Just remember to disconnect the battery first.
What does ‘VIN Programmed’ mean for me?
It means we load your van’s specific Vehicle Identification Number (VIN) and corresponding software onto the module before we ship it. This makes the module ready to install right out of the box, eliminating the need for a costly trip to the dealership for programming.
Will this BCM fix my airbag warning light?
If the airbag light is caused by a communication error with the BCM (like DTC B1001), this module will resolve the root cause. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system and clear the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module without any additional fees or hassle.
