From the Technician’s Bench: We see these late-90s GM computers frequently. A common failure point after 20+ years is the internal capacitors and board traces. They can develop micro-fractures, leading to intermittent problems that are maddening to diagnose. The car might run fine when cold, but stall randomly when hot. This isn’t a mechanical issue; it’s the vehicle’s brain failing. Installing a solid, correctly programmed 1997 Grand Prix PCM 16218070 doesn’t just fix the symptom—it corrects the root cause, providing a lasting and reliable repair.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. The service is included in your purchase. We handle all the programming before the module ships. It will arrive at your door ready for a direct, plug-and-play installation.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is critical for us to program the module correctly for your specific car and its options.
Is this the correct part for my car?
This module is a direct replacement for part numbers 16218070 and 16217058. Please check the fitment list on this page. If your make, model, year, and engine are listed, this is the correct part for your vehicle.
What if my original part number is different but my car is on the list?
That’s very common. GM used several part numbers for the same computer. As long as your vehicle is on our compatibility list, this module, once programmed to your VIN, will function perfectly as the correct replacement.
