Finally, A Simple Fix for Your SUV’s Electrical Problems
Are you tired of dealing with electrical gremlins in your Isuzu Ascender, Trailblazer, or Envoy? Frustrating issues like power windows that won’t cooperate, gauges going haywire, or a vehicle that refuses to start can all point to a failing Body Control Module (BCM).

An Expert’s Insight on GMT360 Electrical Systems
As a technician, I’ve seen countless GMT360 platform vehicles (Trailblazer, Envoy, Ascender, etc.) with bizarre electrical issues that stump owners. The BCM is the central hub for almost all the body and accessory functions. Over time, internal components can fail, leading to the frustrating problems you’re likely facing. Grabbing a used BCM from a junkyard is a gamble; it won’t be programmed for your vehicle’s specific options and VIN, leading to more problems. Our service bridges that gap by providing a fully tested module that is professionally programmed to be a direct, correct replacement, making the repair as simple as possible for the DIYer or professional installer.
Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic functions not related to the engine. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the instrument cluster.
Is this BCM truly plug-and-play?
Yes. Because we program the module using the VIN you provide, it’s ready for installation upon arrival. In most cases, you simply disconnect the battery, swap the modules, and reconnect the battery. However, please review the potential post-installation procedures, as some vehicles may require a simple sync for the airbag or brake systems.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for the programming process.
My original part number isn’t 15114669. Will this still work?
Yes, this module is a direct replacement for several part numbers, including 15122670, 15065293, 15191621, and 9352135. As long as your vehicle is listed in the compatibility chart, we will program the module to function correctly for your specific application.
What if the airbag light comes on after installation?
This can occasionally happen. It simply means the new BCM needs to be synced with the airbag system’s SDM module. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a shop with a professional-grade scan tool. It does not indicate a problem with the BCM itself.
Do I need any special tools to install this 2003-2005 Isuzu Ascender BCM 15114669?
Basic hand tools, such as a socket set and screwdrivers, are typically all that’s required to access and replace the BCM, which is located near the fuse box. Always disconnect the vehicle’s battery before beginning any work.
