Re: Dealer having to replace the PCM
Mine was replaced when my Jeep was a couple of months old. This is during the time that Chrysler was trying to figure out what was causing the "Christmas Tree Dash".
I believe it is the silver colored thing that sits on the right (passenger) side under the hood. It's right up front, looks like a big heat sink, with a bunch of wires plugged in.
It was done in a very short time, while I waited. It was under warranty, so I never paid attention to cost.
Just a reminder ... I said I believe ... I could be wrong.
If you need a shoulder to cry on ...
... pull over to the side of the road!
