Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. This PCM is sold as a plug-and-play solution. We handle all the programming before it ships. All you need to do is provide us with your vehicle’s VIN during or after checkout.
Where is the PCM located on my 1998 Park Avenue?
On most 1998 Buick Park Avenue models, the PCM is located inside the vehicle, under the passenger side of the dashboard, behind the glove box. We always recommend consulting a vehicle-specific service manual to confirm the exact location and procedure before starting your repair.
How do I provide my Vehicle Identification Number (VIN)?
You can add your 17-digit VIN to the notes section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN to ensure we can program your module correctly.
Will this fix my car’s specific problem?
This module will correct any issue directly caused by a failing PCM. While it solves a wide range of drivability problems, it’s essential to ensure your vehicle has been properly diagnosed. If your symptoms match those listed above, there is a very high probability this is the solution you need.
What does ‘PCM’ stand for?
PCM stands for Powertrain Control Module. It’s the main computer that controls both the engine and transmission functions. You may also hear it referred to as an ECM (Engine Control Module) or ECU (Engine Control Unit), but PCM is the most accurate term for this component as it manages the entire powertrain.
Is this part compatible with other GM models?
Yes, this PCM is compatible with a wide range of 1998-1999 GM vehicles that use the same service number. This includes models like the LeSabre, Grand Prix, Lumina, Monte Carlo, and more, as detailed in the compatibility list. We program it specifically for the vehicle you provide the VIN for.
