Are you battling strange and frustrating electrical problems in your GM truck or van? A failing Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, erratic power windows, and mysterious warning messages. The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can make your reliable truck feel unpredictable. This replacement Body Control Module, part number 19208537, is the definitive solution to restore your vehicle’s proper function.
This is not just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures full compatibility with your truck’s options and systems, eliminating the need for a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, loading it with the latest software updates from GM for optimal performance.
We had a 2002 Sierra in the shop that was driving the owner crazy. The interior dome lights would randomly turn on and stay on, draining the battery overnight. He’d already replaced the battery twice and checked all the door jamb switches. After connecting our scanner, we saw erratic data coming from the BCM. We installed one of these VIN-programmed modules, and the problem was solved instantly. It’s a classic example of how a faulty BCM can cause baffling electrical gremlins.
Common Symptoms of a Failing 2002 Silverado Body Control Module
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ Radio or climate control display flickering or going blank.
- ✔ Remote Keyless Entry (RKE) system stops working.
- ✔ A “Service Vehicle Soon” message appearing on the dash.
Installation and Post-Install Considerations
Replacing the BCM is typically a straightforward process. On most 2002 GM trucks and SUVs, it’s located under the steering column. While our VIN programming makes this a plug-and-play repair, some vehicles may require simple post-installation relearn procedures. If the airbag light appears, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary to ensure proper brake light and traction control operation. Best of all, there is no core charge, so you can keep your original module.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to send my VIN after ordering?
Yes. To ensure 100% compatibility and a true plug-and-play experience, we must program the module to your vehicle’s VIN before shipping. Please send us your 17-digit VIN after you complete your purchase.
Will this fix my security light and no-start problem?
A faulty BCM is a very common cause of security system issues on these GM vehicles. By programming this module to your VIN, it correctly syncs with your vehicle’s anti-theft system, which typically resolves these problems.
Where is the BCM located on my 2002 Silverado or Sierra?
On most 2002 GM full-size trucks and SUVs like the Silverado, Sierra, Tahoe, and Yukon, the BCM is located under the driver’s side of the dashboard, typically mounted to a bracket near the steering column.
What if my airbag light comes on after installation?
This can occasionally happen. It means the new BCM needs to be synced with the airbag’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with a professional-grade diagnostic tool.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us.
