1999 – 2000 GM Various Models Body Control Module (BCM) 8162571250 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with that frustrating moment when your 1999 GMC Sierra 1500’s power locks refuse to respond, or the interior lights flicker erratically during a late-night drive? You’re not alone—I’ve seen countless truck owners pull into the shop with similar complaints, often tracing back to a failing body control module. Questions like “why won’t my 2000 Chevrolet Silverado 2500’s windows work properly?” or “how do I resolve intermittent electrical glitches in my 1998 Oldsmobile Bravada?” flood forums and voice searches. The culprit? A worn-out BCM struggling to manage essential systems like lighting, security, and accessories. This pre-programmed BCM, compatible with part numbers including 8162571250, 19153625, 8191536250, 16257125, 191583625, 8093668010, 8191536250, and 09366801, arrives flashed with the latest GM updates using your VIN for a seamless match. It restores reliable operation, preventing those random failures that leave you stranded or dealing with safety concerns. Drawing from over two decades in diagnostics, I’ve analyzed how these modules degrade from moisture exposure or voltage spikes, leading to costly downtime. Opting for this ready-to-install unit saves hours of troubleshooting and ensures peak performance, blending expert precision with user-friendly setup.

Common Issues & How This Fixes Them
In my experience working on GM trucks like the 1999-2000 Sierra or Silverado series, BCM failures often manifest in subtle yet aggravating ways. For instance, you might notice the security system activating randomly, causing a no-start condition that mimics a dead battery—I’ve diagnosed this in a 2000 Astro van where the owner thought it was theft-related, but it stemmed from corrupted module data. Another frequent headache is erratic dashboard warnings, such as persistent airbag lights that won’t clear, often due to communication breakdowns between the BCM and supplemental restraint systems. This can compromise safety, especially on rough roads where vibrations exacerbate internal faults.
Power accessories failing intermittently? That’s a classic sign—windows that roll down but not up, or headlights dimming without reason. Causes range from accumulated heat damage in the center or left-hand dash-mounted unit to software glitches from age. Replacing with this VIN-matched BCM resolves these by refreshing the control logic, ensuring stable voltage distribution and signal integrity. Take a real scenario: A client with a 1999 Isuzu Hombre reported non-functional turn signals during rain; post-replacement, the updated firmware handled moisture better, preventing shorts. For deeper analysis, consider how these modules integrate with the vehicle’s CAN bus network—failures disrupt data flow, leading to DTCs like U1000 or B1480. This part clears those by providing a clean slate, and with proper setup, it minimizes recurrence. Always scan for codes first; if ignored, minor issues snowball into major repairs.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM in the center dash or left-hand dash area, depending on your model.
- Remove the old unit by unplugging connectors and mounting screws; compare it against compatible IDs like 16257125 for confirmation.
- Install the new BCM securely, reconnect all harnesses, and reconnect the battery to power up the system.
- Perform essential post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is needed for optimal braking response—steps vary by model, so reference your manual or a pro if unsure.
- If a no-start occurs due to anti-theft, initiate the relearn by cycling the key from off to on (without starting) for 10 minutes, three times; this aligns the module without special tools in most cases.
