Are you battling a storm of strange electrical issues in your vehicle? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or worse, a car that refuses to start can all point to a failing Body Control Module (BCM). This isn’t just an inconvenience; it’s a breakdown in your vehicle’s central nervous system. We offer the definitive, hassle-free solution: a replacement Body Control Module, professionally programmed to your vehicle’s specific VIN before it ever leaves our facility.
Common Symptoms & Your Solution
A faulty BCM can be difficult to diagnose because its symptoms often mimic other problems. If you’re experiencing any of the following, this module is the likely solution:
- Interior or exterior lights not working correctly (staying on, not turning on, or flickering).
- Power windows, door locks, or mirrors behaving erratically or not at all.
- The security system or anti-theft light is preventing the engine from starting.
- Dashboard warning lights appearing for no reason.
- Inconsistent or non-functional remote keyless entry.
This Programmed Body Control Module 20815898 is the direct answer to these problems. By providing us with your VIN at checkout, you receive a unit that is a true plug-and-play component, saving you from a costly and time-consuming trip to the dealership for programming.

Expert Insight: The Smarter Repair
From over 20 years of experience, I’ve seen countless vehicle owners chase electrical gremlins, replacing bulbs and switches only to find the root cause was the BCM. A failing BCM creates a domino effect of issues. Choosing a junkyard module might seem cheaper upfront, but it will still require programming at a dealership, often costing hundreds of dollars. Our Programmed Body Control Module 20815898 provides a new-component level of reliability and skips that expensive final step, making it the most efficient and cost-effective repair for both DIYers and professional shops.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer in your car that controls and monitors many of the non-engine related functions. This includes power windows, power mirrors, air conditioning, the anti-theft system, central locking, and interior/exterior lighting. When it fails, these systems can become unreliable.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will I need to perform any procedures after installation?
In some cases, yes. Depending on your specific vehicle, you may need a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light comes on, or a ‘Brake Pedal Position Relearn’. These are known as post-installation procedures and are sometimes necessary to sync the new BCM with other vehicle systems.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, replacing a BCM is generally straightforward. The location varies by model (e.g., center dash, under the steering column). The most important step is disconnecting the battery before you begin. Because our module comes programmed, the most complex part of the job is already done for you.
What if my original part number is not on your list?
The provided list of part numbers (10382479, 15093910, 20815898, etc.) covers all known interchanges. If your number is on this list, this module is the correct replacement. If you are unsure, please contact us with your VIN and original part number, and we will be happy to verify compatibility for you.
