Is Your 2004 Savana 1500 Running Rough or Not Starting at All?
As a mechanic with over two decades of experience, I know how frustrating it is when a reliable workhorse like the Savana van starts acting up. You might be dealing with a persistent Check Engine Light, erratic shifting, stalling, or a complete no-start situation. Often, the root cause isn’t a bad sensor or fuel pumpโit’s the brain of the operation: the Powertrain Control Module (PCM).
From the Shop Floor: A Real-World Scenario
“A customer’s 2004 Savana 1500 came in last week with a classic no-start, no-spark condition. They had already replaced the ignition coil and crank sensor, but nothing worked. After a quick check with the scope, I saw the PCM wasn’t sending the command to fire the coils. The internal driver had failedโa common issue on these units after years of heat cycles. We installed one of our pre-programmed modules, and the van fired right up. Itโs a fix Iโve performed hundreds of times, saving customers from chasing phantom problems.”
