| Description of the problem | Difficult to diagnose! Symptoms of a wet pcm module manifests itself in many forms. We've experienced most of them by this point in our ~3 year battle with our freestar. Randomly, our van would not: start, go into reverse, give warning lights, drive forward without stalling, allow certain systems to function properly. In other situations, it would: run roughly, break down, rev up unexpectedly, create transmission issues, etc. Seals wear down and allows water to enter into the computer, due to its location under the windshield. One of the greatest problems of all is the lack of diagnostics for this issue. We've had our vehicle towed in, only to find diagnostic codes did not show up when the van was checked out. Surprisingly, the car would usually start up and drive without a problem after being towed into the mechanic. After several towing experiences, we simply decided to leave our car stranded for a day or two if possible and return later to drive it away without a problem. We've replaced pumps, coils, transmission components, plugs, wires.. In an effort to get the van to work properly. Finally, one mechanic did on-line research and found the pcm problem with the 2005 freestar. After finding water in the computer housing, he suggested that we buy a rebuilt one (ford does not supply pcm's for this van anymore) to see if that would solve the problems. However, the ford dealership had to install the computer so that the programming could be completed. Otherwise, the original keys would not work. In summary, the pcm did solve the problems, until the next weather event. Then, the problems started all over again. We have now had the computer replaced, dried, and/or sealed several times, but water keeps getting inside. The local ford dealership and other mechanics have been working diligently in an effort to seal the pcm. Recall and class action needed! |
