To replace the PCM (Powertrain Control Module) on a 2007 Chevy Cobalt, first disconnect the negative battery cable to ensure safety. Remove the PCM by locating it, usually found near the engine bay or under the dashboard, and disconnect the wiring harness and mounting bolts. Install the new PCM by connecting the wiring harness and securing it with the bolts. Finally, reconnect the negative battery cable and ensure the vehicle's computer is reprogrammed with the correct software if necessary.
