Is Your 1996 GM Vehicle Running Rough?
If you’re dealing with frustrating issues like intermittent stalling, a persistent check engine light, harsh shifting, or a complete no-start condition in your 1996 Buick Park Avenue or a similar GM model, the Powertrain Control Module (PCM) is often the culprit. Over time, the internal components of these modules can fail, leading to a host of drivability problems that can be difficult to diagnose. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded.
The Direct-Fit, Programmed Solution
This is a replacement Powertrain Control Module, part number 16211539, designed to restore your vehicle’s original performance and reliability. The biggest challenge with replacing a PCM is the need for expensive dealership programming. We eliminate that step entirely. Before we ship your module, our technicians will program it with the latest GM software updates using the unique Vehicle Identification Number (VIN) from your car. This ensures it communicates perfectly with your engine, transmission, and all related systems right out of the box.
“A customer’s ’96 LeSabre with the 3.8L V6 came in last week with these exact symptoms: it would crank but not start, and when it did run, it shifted erratically. The owner had already replaced the fuel pump and filter. We connected our scanner and found a ‘No Communication with PCM’ error. After verifying power and ground at the module connector, we knew the internal board had failed. Swapping in a pre-programmed module like this one resolved all the issues instantly. It’s a common failure point I’ve seen hundreds of times on these mid-90s GM vehicles.”
