Once you inspect and clean every little connector, throw a dab of Vaseline into it as you plug it back in to whatever it goes too. It'll keep moisture out.. Then throw a dab of RTV to the backside of the connector where the wires lead into the connector. You'll notice that although some connectors have a rubber seal... moisture gets in through the back.... Go look at your 02 sensor connectors... You'll see what I mean.
Chrysler spent millions over the years redesigning, and updating Dodge vans when it comes to appearance, safety, and efficiency... Yet hired a comedian to redesign the electrical system.
And in the end, in case you didn't catch my latest post, you were correct, basically. As it turned out, the gasket for the pcm was badly deteriorated and even the two halves of the pcm were pulled apart with a pretty good sized gap in some places. That, I believe was the key factor for the circuit board having a lot of corrosion. Many of the soldered contact points on the board, including those for some of the pins were broken. Needless to say, I had the pcm rebuilt and my van is back to running like a top. What an ordeal!
