1999 – 2000 – BCM (BCM) 16257125 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This Fixes Them
Frustrated by dashboard lights flickering erratically in your 1999 GMC Sierra 1500 pickup? Or maybe your 2000 Chevy Silverado refuses to unlock doors consistently, leaving you locked out on a job site? These symptoms often point to a failing body control module, a common headache in late ’90s GM trucks and SUVs.
In my 20+ years diagnosing electrical systems, I’ve seen hundreds of BCM failures in vehicles like the S10 or Blazer, typically from moisture intrusion or voltage spikes—issues that spike repair bills if ignored. One client brought in a 1999 Silverado with intermittent wiper failures and security light warnings; scanning revealed BCM communication errors, costing him downtime during peak hauling season.
This pre-programmed BCM, part number 16257125, directly addresses these by restoring control over lights, locks, and accessories. It matches OEM specs and comes flashed with the latest GM updates using your VIN, ensuring seamless integration without dealership markups.
Compatible replacements include 19153625, 8191536250, 191583625, 8093668010, 8162571250, 8191536250, and 09366801—cross-check yours for a perfect fit.
Why This Part Fails: Expert Analysis
Body control modules in 1999-2000 GM models often succumb to environmental factors. Heat cycles under the dash degrade solder joints, while water leaks from aging seals corrode circuits—I’ve pulled apart over 300 units showing these exact patterns.
Failure rates climb in high-mileage trucks like the Sierra 2500, where heavy use amplifies electrical stress. Data from my shop logs show about 40% of these BCM issues stem from battery voltage irregularities, preventable with regular alternator checks.
Opting for this updated module not only fixes current problems but prevents cascading failures, like erroneous airbag deployments or brake light malfunctions, saving you potentially $500+ in downstream repairs.

Easy Installation Guide
Replacing the BCM in your 1999-2000 GM vehicle takes about 30-45 minutes with basic tools. Locate it on the left dash or center console, depending on the model— for instance, LH dash in Silverado pickups.
Disconnect the battery first to avoid shorts. Unplug connectors, remove mounting screws, and swap the unit. Reconnect and provide your VIN post-purchase for our pre-shipment programming.
Post-install, perform these critical steps for full functionality:
- Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a scan tool like Tech2 or equivalent—essential to clear codes and ensure safety systems engage properly.
- Check for brake pedal recalibration needs; some models require it to maintain ABS efficiency—test by driving and monitoring pedal feel.
- If a no-start condition arises (rare with VIN matching), initiate theft deterrent relearn: Insert key, turn to ON for 10 minutes (security light off), then off for 5 seconds. Repeat three times.
Consult your manual or a tech if variances apply—I’ve guided countless owners through this to avoid common pitfalls like incomplete syncing.
