Ok i need to know what PCM stands for and where its located, a pic would help alot... i have search and found nothing that can help me figure where it is... i would like some good detail so i can spot it out quickly. thanks
 
PCM stands for powertrain control module, aka the ecu. It is located in the console just under the radio. If you pull the side panel from the console, you will see it bolted to the metal console frame.
 
Technicly these cars don't use a PCM, they use an ECU (engine control unit) or ECM (engine control module). A PCM would control the entire powertrain as in engine and transmission. Even the auto cars use a seperate TCM (transmission control module).

Not that it's really important because everyone will know what you're talking about, but it's just something to know :)
 
which side is this PCM on? and how do i get it into diagnostics mode?

With your car it is on the driver side of the engine bay. As for checking codes, the best way is to use a scanner. I haven't personally tried this on a 420a car, but on most Chrysler cars you can initiate a diagnostic mode by turning the key in a pattern. You can try this and see if it will work on your are. It will be on, off, on, off, on. Do this within 5 seconds of the first time you turn the key on. If it works properly than the check engine light will flash the code. As i said though, i have not verified this to work with a 420a car, but it is worth a shot.
