Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your GMC Safari, Chevy Astro, Silverado, or other GM truck/van? Symptoms like erratic power windows, malfunctioning door locks, flickering interior lights, or a security system that prevents the engine from starting often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM, part number 19208537, is the definitive solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We had a 2004 GMC Safari in the shop that was driving the owner crazy. The dome lights would randomly stay on, draining the battery overnight. He’d already replaced the battery twice and checked all the door jamb switches. After connecting our diagnostic scanner, we saw communication errors pointing to the BCM. We installed one of these pre-programmed modules, and the problem was solved instantly. The lights worked perfectly, and the owner was relieved to finally have a reliable van again. It’s a classic case of a faulty BCM causing a simple but maddening problem.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security or anti-theft system light is on, causing a no-start condition.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Wipers operating intermittently or not parking correctly.

We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships.

You avoid expensive dealership programming fees and lengthy service appointments. Simply provide your VIN during checkout, and we’ll handle the rest.
Installation and Post-Install Notes
On most GMC Safari and Chevy Astro vans, the BCM is located behind the center of the dashboard. While installation is straightforward for a seasoned DIYer or technician, please be aware of potential post-installation procedures that may be required for your specific vehicle:
- Airbag System Sync: If your 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: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
