Are you battling frustrating electrical problems in your GM truck or van? Issues like erratic power windows, a security system that won’t cooperate, or dashboard lights that have a mind of their own are often traced back to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and annoying symptoms. This replacement Body Control Module, part number 19208537, is the definitive solution to restore your vehicle’s proper function and reliability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures compatibility with your vehicle’s options and systems, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we handle the rest.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ The security or anti-theft system prevents the vehicle from starting.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Windshield wipers behaving erratically.

Important Post-Installation Information
While this BCM is designed for a simple installation, some vehicles may require additional steps to ensure all systems function correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified automotive technician if you are unsure about any part of the installation process.
