Is Your Trusty Astro Van Suddenly Unreliable?
A failing Powertrain Control Module (PCM) can turn your dependable 1998 Chevy Astro into a source of constant frustration. If you’re dealing with a persistent Check Engine Light, a van that won’t start, rough idling, stalling, or a sudden drop in fuel economy, the engine’s brain is likely the culprit. Don’t let a faulty computer keep you off the road. This is the straightforward, reliable solution to get your vehicle running smoothly again.

- Erratic automatic transmission shifting
- Check Engine Light with communication error codes (like U-codes) or multiple sensor codes

An Expert’s Note on Late ’90s GM Computers
Back in the late 90s, GM’s vehicle security systems, like Passlock, became deeply integrated with the PCM. Simply swapping a computer from another vehicle won’t work—the engine won’t start because the security systems won’t match. That’s why our VIN programming service is so essential. We don’t just send you a part; we deliver a component that is electronically matched to your specific Astro, making the installation process as simple as possible for you.
This module is the correct, programmed solution for a wide range of GM trucks and vans. Please verify your part number or consult the detailed fitment list to confirm compatibility. Getting your hands on a properly programmed 1998 Chevy Astro PCM 16250279 is the most important step in bringing your vehicle back to life.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive and program it with this information.
Will I need to do any extra programming after I install it?
No. Because we program the PCM to your specific VIN before shipping, it should be ready to install and function immediately. In some cases, a security relearn procedure may be required, which is a simple process that can be done without special tools.
How do I find my original part number?
Your vehicle’s original PCM part number is printed on a sticker on the module itself. The module is typically located in the engine bay, on the driver’s side near the battery. Matching this number to our list ensures a perfect fit.
Is this part difficult to replace?
Replacing a PCM is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. However, we always recommend consulting a repair manual or a professional technician if you are unsure.
What does a ‘used’ part mean for an electronic module?
This means the part was carefully removed from a functioning, salvaged vehicle. Each unit is inspected and then completely reprogrammed with fresh, updated software for your specific vehicle, providing a reliable and affordable alternative to a new part.
