Is Your GM Vehicle Acting Possessed?
Are you battling bizarre electrical gremlins in your GMC Savana, Chevy Express, or other GM vehicle? Flickering lights, malfunctioning power windows, a dead key fob, or a dashboard that’s lit up with random warnings are all classic, frustrating signs of a failing Body Control Module (BCM). These issues can make your vehicle unreliable and unsafe, turning every drive into a guessing game. Don’t let a faulty module dictate your day or lead to an expensive, time-consuming dealership visit.
Common Symptoms of a Failing BCM & Your Direct-Fit Solution
If you’re experiencing any of the following, a faulty BCM is the most likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior dome lights or exterior headlights acting erratically.
- Vehicle security system randomly activating or preventing the engine from starting.
- Keyless entry remote (fob) has stopped working.
- Instrument cluster gauges giving inaccurate readings or warning lights staying on.
- Diagnostic Trouble Codes (DTCs) related to communication loss (U-codes).

A Technician’s Perspective: Why Pre-Programming is a Game-Changer
In the past, replacing a BCM was a job reserved for the dealership. You’d buy the part, have your vehicle towed in, and then pay hundreds in labor for a technician to use a specialized scan tool to “introduce” the new module to the vehicle. Without this step, the car simply won’t run. Our pre-programming service for the Programmed GM Body Control Module 20815898 completely changes that. We handle the complex software side for you, turning a multi-day, high-cost ordeal into a straightforward component swap you can often perform yourself. It’s the smartest way to get your vehicle back to 100% without the dealership price tag.
Frequently Asked Questions
Do I need to send you my old BCM?
No. This part is sold without a core charge. You can keep or dispose of your original module at your convenience, saving you time and return shipping costs.
How do I provide my VIN number?
You can add your 17-digit Vehicle Identification Number (VIN) to the notes section during the checkout process. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship your module.
Is any extra programming required after I install it?
Our service covers the main programming, making the unit ready for installation. However, on some GM models, you may need a qualified technician with a professional scan tool to perform a quick relearn procedure, such as the “Setup SDM Primary Key in BCM” for the airbag system or a “Brake Pedal Position Relearn.” This is only necessary if specific warning lights appear after installation.
Will this fix my specific problem?
A failing BCM is the cause of a wide array of electrical issues. While this Programmed GM Body Control Module 20815898 is the correct solution for those faults, we always recommend that a proper diagnosis is performed to confirm the BCM is the root cause before ordering.
What if my original part number isn’t on the list?
Please contact us with your VIN. GM frequently updates and consolidates part numbers. The list provided is extensive, but we can verify 100% compatibility for your specific vehicle to ensure you get the right part the first time.
Is this a new or used part?
This is a high-quality, fully tested component. Each module is thoroughly inspected and verified to meet or exceed original specifications before being programmed and shipped to you.
