Restore Full Electrical Function to Your GM SUV
Is your Chevrolet Trailblazer, GMC Envoy, or Oldsmobile Bravada suffering from bizarre electrical problems? Unpredictable power windows, flickering lights, or malfunctioning gauges are often the first signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating issues. This replacement BCM, part number 15065293, is the definitive solution to get your truck’s systems working in harmony again.
We take the guesswork and high cost out of the repair process. Unlike a standard replacement that requires an expensive trip to the dealership for programming, this module arrives at your door pre-programmed to your vehicle’s specific VIN. We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This plug-and-play approach saves you time, money, and the headache of coordinating with a service center.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely culprit. Replacing it can resolve these problems and restore your vehicle’s reliability.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Wipers operating intermittently or not turning off.
- ✔ HVAC (heating and air conditioning) control problems.
- ✔ Diagnostic Trouble Codes (DTCs), especially U-codes, indicating a loss of communication.
From the Diagnostic Bay
We had a 2004 GMC Envoy come into the shop with a complaint the customer called ‘the ghost in the machine.’ The radio would change stations on its own, the driver’s side window would roll down overnight, and the horn would honk randomly. After checking for wiring shorts and finding none, we scanned the system and saw multiple communication loss codes pointing to the BCM. A quick swap with a pre-programmed Trailblazer Envoy BCM like this one solved every single issue. The customer was thrilled to have their well-behaved truck back, free of any paranormal activity.
Why Choose Our Programmed Trailblazer Envoy BCM?
This isn’t just a part; it’s a complete solution. By providing us with your VIN during checkout, you receive a module that is precisely matched to your vehicle’s factory options. This critical step ensures all existing features work as intended without any additional calibration for most functions. This unit is a direct replacement for a range of part numbers, including 15122670, 15065293, 15114669, 15191621, and 9352135, guaranteeing a perfect fit for your application.
Simple Installation Process
Installation is straightforward for a DIY mechanic or any professional technician. The BCM is typically located in or near the front fuse box. Once the new module is installed, you may need to perform a couple of simple relearn procedures depending on your vehicle’s specific configuration.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This simply means the new BCM needs to be synced with the airbag’s SDM module. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Plus, with our no-core-charge policy, you can keep your original module without the hassle of shipping it back.
Frequently Asked Questions
Is this BCM ready to install out of the box?
Yes! This BCM is pre-programmed to the VIN you provide, making it a plug-and-play solution for most vehicles. This eliminates the need for a costly trip to the dealership for programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN, as the programming is specific to your vehicle.
Will this fit my 2005 Isuzu Ascender?
Yes, this module is compatible with a wide range of 2002-2005 GM mid-size SUVs, including the Isuzu Ascender, Chevy Trailblazer, GMC Envoy, Oldsmobile Bravada, Buick Rainier, and Saab 9-7X. Please check the detailed fitment list on this page to confirm your specific model and options.
What if the airbag light is on after I install it?
If the airbag light comes on, it’s not a defect. The new BCM simply needs to be electronically introduced to the airbag system. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off 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, which can be helpful for reference or as a backup.
