Is Your Alero, Grand Am, Cavalier, or Sunfire Running Rough?
If you’re dealing with a persistent Check Engine Light, erratic engine behavior, stalling, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). As a technician with over two decades of experience under the hood, I’ve seen how a faulty PCM can turn a reliable car into a source of constant frustration. It’s the brain of your engine, and when it malfunctions, nothing else works correctly. This isn’t just an inconvenience; it affects your car’s performance, fuel economy, and safety.
The Simple, Reliable Solution: A Pre-Programmed PCM
Forget expensive dealership visits and the hassle of finding a shop that can program a replacement module. We offer a straightforward solution: a thoroughly tested, used OEM PCM that arrives at your door pre-programmed and ready for installation. We use your vehicle’s VIN to flash the module with the latest GM software updates, ensuring it communicates perfectly with your car’s specific systems right out of the box.
Expert Pro Tip from 20+ Years in the Shop:
Before you swap out your PCM, take a moment to inspect the main ground wire connections for the engine and chassis. On these GM platforms, a corroded or loose ground (especially the one near the engine block or transmission) can cause voltage drops that mimic PCM failure. I’ve seen dozens of cases where a simple $5 wire brush and five minutes of cleaning saved a customer from replacing a perfectly good module. A clean, tight ground ensures the new PCM gets the stable power it needs to operate flawlessly.

Plug-and-Play Installation: No Dealer Visit Required
Replacing the PCM on these vehicles is a manageable job for a DIYer. Here’s a general guide to get you started:
- Safety First: Disconnect the negative terminal from your car’s battery and wait at least 15 minutes for any residual power to discharge.
- Locate the Old PCM: On the Alero and Grand Am, it’s typically found behind the glove box or in the center console area (LH center dash). On the Cavalier and Sunfire, it’s usually in the engine compartment (RH front or rear).
- Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins on the harness for any corrosion or damage before proceeding.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place and securely reconnect the wiring harnesses. You should hear a distinct click.
- Reconnect the Battery: Reattach the negative battery terminal. Your vehicle is now ready to start. A security relearn procedure may be required, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.
