how do you replace the PCM on a 2003 Chrysler Town & Country 303 engine?
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...
..you may also buy them online programmed to your car, plug+play, for a reasonable price
where is it located. I think it is near the battery but I want to be sure.
