Is Your Trailblazer Experiencing Bizarre Electrical Issues?
Are you tired of your Trailblazer’s unpredictable electrical behavior? Power windows with a mind of their own, flickering lights, random warning messages on the dash, or door locks that refuse to cooperate? These frustrating and often confusing problems typically point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your SUV’s body electronics, and when it starts to fail, it can create a cascade of annoying and potentially unsafe issues. Instead of paying for expensive diagnostic time and programming fees at a dealership, get the definitive, pre-programmed solution delivered right to your door.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, our pre-programmed module is the reliable fix you need:
- Erratic power windows, locks, or mirrors
- Interior or exterior lights not working correctly (staying on or not turning on)
- Intermittent or non-functional radio and instrument cluster gauges
- False security system alarms or starting issues
- Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes)
This Programmed 15135466 Trailblazer BCM is the direct answer to these problems.

An Expert’s Take on GMT360 BCMs
As a technician, I’ve seen countless GMT360 platform vehicles like the Trailblazer, Envoy, and Rainier come into the shop with baffling electrical problems. The BCM in these trucks is located in the front fuse box, an area that can sometimes be susceptible to moisture or voltage spikes from a failing alternator. Over time, these factors can corrupt the module’s internal logic. In the past, the only fix was a new module and a trip to the dealer for programming. Our solution changes the game. By providing a quality, tested Programmed 15135466 Trailblazer BCM, we empower owners and independent shops to perform this repair efficiently, restoring the vehicle’s reliability without the dealership price tag.
Frequently Asked Questions
What does “VIN-programmed” mean?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and factory-correct software onto the BCM before we ship it. This ensures the module communicates correctly with your SUV’s other computers, like the engine control module and instrument cluster, for a seamless installation.
Do I need to send my old BCM back?
No. This purchase comes with no core charge. You can keep your original part, which saves you the time, cost, and hassle of shipping a core back to us.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag warning light is on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This is a simple sync that a qualified technician can perform.
Is any other programming required after I install it?
Our goal is a plug-and-play installation. However, depending on your specific model, a Brake Pedal Position Sensor relearn may be necessary to ensure proper brake light and traction control operation. This is a common procedure that can be done with a capable diagnostic tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your BCM without this information.
Will this fit my 2007 GMC Envoy?
Yes, this BCM is compatible with a wide range of GM SUVs from this platform, including the GMC Envoy, Isuzu Ascender, Buick Rainier, and Saab 9-7X. Please check the detailed fitment list in the description to confirm compatibility with your exact year and options.
