Is Your 1996 GM Vehicle Running Rough, Stalling, or Throwing Confusing Codes?
If you’re dealing with frustrating issues like intermittent no-starts, poor fuel economy, erratic transmission shifting, or a persistent Check Engine Light in your 1996 Lumina or other compatible GM model, a failing Powertrain Control Module (PCM) is a very common cause. Over my 20+ years in the shop, I’ve seen hundreds of these mid-90s vehicles where the original engine computer simply gives out due to age, heat cycles, and internal component degradation. Drivers often waste money on new sensors, only to find the root problem was the vehicle’s brain all along.
This isn’t just a replacement part; it’s a direct solution. We are providing a dependable PCM, service number 16211539, that arrives at your door specifically programmed for your vehicle. You provide us with your Vehicle Identification Number (VIN) during checkout, and we flash the module with the latest official GM software updates. This critical step ensures all parameters for your specific engine, transmission, and options are loaded correctly, eliminating the need for an expensive trip to the dealership for programming.

Expert Pro Tip: Check Your Connectors
Before you install your new PCM, take a moment to inspect the vehicle’s harness connectors. Over 25+ years, it’s common for the pins to develop a thin layer of green or white corrosion, or for the plastic to become brittle. Use a small pick and some quality electronics cleaner to gently clean each pin socket. A poor connection is one of the few things that can make a perfectly good new module appear faulty. This five-minute check can save you hours of diagnostic headaches.
Simple Plug-and-Play Installation Guide
Replacing the PCM on these vehicles is a job most DIY mechanics can handle in under an hour with basic tools. Follow these steps for a smooth installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- Locate the PCM: On most 1996 GM cars like the Lumina, the PCM is located inside the air filter housing. You will need to remove the air filter cover and filter to access it.
- Disconnect the Harness: Carefully unplug the electrical connectors from the old PCM. There are typically two or three large multi-pin connectors with locking tabs. Be gentle to avoid damaging the aged plastic.
- Remove the Old Module: Unbolt the PCM from its mounting bracket or housing and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed PCM in the same location and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Start: Reassemble the air filter housing, reconnect the negative battery terminal, and start the vehicle. It may run a little rough for the first few minutes as it completes its idle relearn process.
