Restore Your Vehicle’s Electrical System with Confidence
Are you battling frustrating and unpredictable electrical problems? Flickering lights, malfunctioning power windows, a security system that acts on its own, or dashboard warnings that make no sense are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s comfort and convenience features. When it fails, it can make your daily drive a stressful experience. This isn’t just an inconvenience; it can affect your vehicle’s security and basic functions. Stop guessing and replace the faulty component with a reliable, pre-programmed solution.

Expert Insight: The ‘Brain’ of Your Car’s Body
Think of the BCM as the central nervous system for all non-engine related electronics. It manages the communication between dozens of switches, sensors, and accessoriesโfrom the simple press of your window switch to the complex logic of the anti-theft system. That’s why a failing BCM causes such a wide array of strange symptoms.

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your VIN. You can also add it as a note to your order during checkout to speed up the process. We cannot ship the module until we have programmed it.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. The location varies by model (e.g., under the dash, behind the glove box). Since we handle the programming, you’ve already bypassed the most difficult part of the repair. However, some vehicles may require a simple ‘relearn’ procedure for the brake pedal position sensor or airbag system, which can be done with a compatible scan tool.
What if the airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This is a security feature. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Will this fix every electrical problem in my car?
This module will resolve any issue directly caused by a faulty BCM. While the symptoms listed are strong indicators, it’s always best to have a proper diagnosis performed to rule out other potential causes like bad wiring, faulty switches, or blown fuses. This Programmed 20935349 Body Control Module is the correct fix when the BCM itself has been identified as the point of failure.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep, discard, or recycle your original module at your convenience without any extra fees or penalties.
