Restore Full Control and Reliability to Your GM Truck or Van
Are you battling frustrating electrical gremlins in your workhorse? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own can bring your work to a halt. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s electronics. This isn’t just an inconvenience; it’s a reliability issue that costs you time and money. Get your truck or van back in dependable service with our pre-programmed BCM, designed to be a direct, effective solution.
Common BCM Failure Symptoms & Your Direct Solution
A faulty BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, this module is the likely solution you need:
- Intermittent or non-working power windows, door locks, or interior lights.
- Erratic instrument cluster behavior or warning lights that won’t turn off.
- The security system preventing the vehicle from starting (anti-theft light flashing).
- Problems with the radio or climate control functions.
- Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes).
Instead of paying for expensive diagnostic time and dealership programming fees, this module arrives ready for installation. We use your vehicle’s VIN to flash the BCM with the latest GM software updates, ensuring it communicates perfectly with your truck’s existing systems right out of the box. This is the professional-grade fix for your 2003-2007 Express 3500 BCM and other compatible GM models.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless people try to save a few dollars by installing a used BCM from a salvage yard. It almost never works. Since the early 2000s, GM has integrated these modules into the vehicle’s anti-theft and communication networks. A BCM is ‘locked’ to the VIN of its original vehicle. Installing a mismatched module will, at best, not function correctly, and at worst, prevent your truck from starting at all. Our service takes that critical failure point out of the equation. By programming the 2003-2007 Express 3500 BCM to your specific VIN, we are delivering a component that is electronically identical to a brand-new part from the dealer, ready to integrate seamlessly.
Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
Is this BCM truly ‘plug and play’?
Yes, for the vast majority of vehicle functions. Because it is programmed to your VIN, it will control the power accessories correctly upon installation. However, as with any BCM replacement on these models, certain safety systems may require a ‘relearn’ procedure with a professional scan tool. This can include the ‘Setup SDM Primary Key in BCM’ for the airbag system or a ‘Brake Pedal Position Relearn’. These are only required if you have related warning lights after installation.
Will this fix my specific electrical problem?
This module will resolve any issue directly caused by a failing BCM. The symptoms listed above are the most common indicators. While this part is a very common solution, we always recommend having a qualified technician properly diagnose your vehicle to confirm the BCM is the root cause of your problems before ordering.
Do I have to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, which saves you time and return shipping costs.
What if my original part number isn’t 15194169?
That’s okay. This BCM is a direct replacement for a range of part numbers. Please check the fitment list on this page. As long as your original part number is on our cross-reference list, this module will work perfectly for your vehicle. The programming for your specific 2003-2007 Express 3500 BCM or other model is what ensures perfect function.
