Is Your Chevy Truck or Van Acting Up?
If you’re dealing with a frustrating no-start condition, erratic engine behavior, a persistent check engine light, or poor fuel economy in your 1998-1999 GM vehicle, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer, when the PCM starts to fail, it can create a host of issues that are impossible to ignore. I’ve seen it hundreds of times in the shop: a customer comes in after replacing sensors and pumps, only to find the root cause was the PCM itself.
The Smart, Affordable Solution for Your 1998-1999 Chevrolet 2500 PCM
Forget the massive expense and hassle of a dealership visit. This is a reliable, tested, and used OEM Powertrain Control Module that gets you back on the road without the dealership price tag. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN. This means it arrives at your door ready for installation, loaded with the latest GM software updates to ensure optimal engine performance and transmission shifting.
Expert Pro Tip: Check Your Grounds Before Installation
Before you install your replacement PCM, take 10 minutes to inspect and clean the main engine-to-chassis and battery-to-chassis ground straps. On these GMT400 and Express/Savana platforms, corroded or loose grounds are a notorious cause of electrical gremlins and can damage a new module. A simple wire brush cleaning at the connection points can prevent a world of headaches.

Simple Installation Guide
Installing your replacement 1998-1999 Chevrolet 2500 PCM is a straightforward job you can do with basic hand tools. While the exact location varies slightly by model, it’s typically found in the engine bay.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On most pickups (Silverado, Sierra, Tahoe, Yukon), it’s on the driver’s side of the engine compartment near the firewall or fender. On vans (Express, Savana), it’s often in the LH rear engine compartment.
- Disconnect the Harnesses: Carefully unclip the electrical connectors from the old module. Inspect the pins for any corrosion or damage before proceeding.
- Remove the Old Module: Unbolt the mounting bracket holding the PCM in place and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM, reconnect the electrical harnesses securely, and re-attach your battery terminal. Your vehicle is now ready to start.
