Are you experiencing frustrating electrical problems in your Saturn Vue or other GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind issues like flickering interior or exterior lights, malfunctioning power windows and locks, erratic instrument cluster behavior, or even a no-start condition. The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, part number 15921352, is the definitive solution to restore your vehicle’s proper function.
We take the guesswork and high cost out of the repair process. Unlike a dealership that requires you to have the vehicle towed in for expensive programming, we program this module to your vehicle’s specific VIN before we ship it to you. This means it arrives ready for installation, saving you time, money, and hassle. Simply provide us with your VIN after purchase, and our technicians will load the latest GM software updates, ensuring optimal performance and compatibility.
We had a 2009 Chevy Traverse come in with a classic parasitic battery drain. The owner had already replaced the battery twice and the alternator once, but the vehicle would still be dead every morning. After a quick diagnostic, we traced the drain to the BCM. It wasn’t fully ‘sleeping’ when the car was off, keeping several circuits active and slowly draining the new battery. Swapping in a VIN-programmed BCM like this one solved the problem instantly. It’s a reminder that what seems like a battery issue can often be a computer problem in modern cars.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system acting up, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with other modules, often triggering multiple warning lights.
- ✔ A persistent battery drain that kills the battery overnight.
Installation and Setup for your 2008-2010 Vue BCM
Installation is straightforward. Once the new module is physically installed, it will be plug-and-play for most functions. However, due to the complexity of modern vehicle systems, some models may require a simple ‘relearn’ or ‘synchronization’ procedure for specific systems. Most commonly, this involves the airbag (SRS) system or the brake pedal position sensor. If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick step for any qualified shop. This module is a direct replacement for a wide range of part numbers, ensuring broad compatibility across many GM models. Please see the extensive fitment list to confirm this part is right for your vehicle.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before shipping. Just provide your vehicle’s VIN during or after checkout, and the module will arrive ready to install.
What does the Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and instrument cluster functions.
Is this part truly plug-and-play?
For most functions, yes. Because it’s programmed to your VIN, it will immediately communicate with your vehicle. However, in some cases, simple relearn procedures for systems like the airbags or brake sensor may be required, as noted in the product details.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
What if my airbag light is on after I install the BCM?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system. A repair shop with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
