how do you replace the PCM on a 2003 Chrysler Town & Country 303 engine?

Asked by Guru9M3C9 Jul 25, 2017 at 02:03 PM about the 2003 Chrysler Town & Country LX FWD

Question type: Maintenance & Repair

Check engine light indicates fault in PCM.  I'm told I can still drive it for a while but eventually it will cause problems.  I am trying to find out where it is located on the vehicle and is it something I can replace.  I see the PCM parts advertised for a lot less than the mechanic shop is charging.

I would have the PCM changed by the shop, you will need to have it programmed as well and they will have the tools to do the job...

If you find the PCM please let me know where you found it. I can't find mine, There is no PCM by my battery, I found something under the left fender but I don't think it is the PCM. It does not look like the pics I have seen. Maybe it is missing, that is why no spark.
