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

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

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...
