Restore Full Functionality to Your GM SUV’s Electronics
Are you battling frustrating electrical gremlins in your GMC Envoy, Chevy Trailblazer, or other compatible GM SUV? Issues like flickering lights, unresponsive power windows, or a mysterious battery drain often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of confusing and inconvenient problems. This replacement Body Control Module, part number 15065293, is the definitive solution to restore your vehicle’s performance and your peace of mind.
Is Your 2002-2005 Envoy XL BCM Failing?
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following issues, a failing BCM is the likely cause:
- ✔ Intermittent or completely dead power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Windshield wipers operating incorrectly or not at all.
- ✔ Malfunctions in the climate control system.
- ✔ A security or anti-theft light that stays illuminated, preventing the engine from starting.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (U-codes).
The Plug-and-Play Solution: Programmed to Your VIN
Don’t waste time and money at the dealership with expensive programming and labor fees. We make this repair straightforward. When you purchase this BCM, we program it specifically for your vehicle using the VIN you provide. This ensures that all the factory-installed options and security information are correctly loaded into the module. The result is a part that is ready for installation right out of the box, drastically simplifying the repair process. There is no core charge, so you can keep your original module.
Installation and Post-Install Procedures
After installing your new BCM, a couple of simple relearn or synchronization procedures may be necessary to ensure all systems communicate correctly. These are standard procedures for this type of repair.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure proper brake light and traction control operation.
Please note: While many installations are seamless, specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, wipers, the security system, and climate controls.
Is this BCM really plug-and-play?
Yes! We program the module with the latest GM software using the VIN you provide at checkout. This ensures it matches your vehicle’s specific options, making installation as simple as possible without needing a trip to the dealer for programming.
How do I give you my 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 programming.
What if the airbag light is on after I install it?
This is a common occurrence. The new BCM needs to be electronically introduced to the airbag system. A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
