if worst comes to worst and i do end up replacing the PCM in my 99 Durango after testing literally everything else. the part number for the PCM is what im unsure about is it the same as any or are there different PCM Part #'s if so what could they be, my current PCM has no stickers ive taken it completely out and checked for a number which does not exist

 

Usually when you order a PCM they should also ask for the trucks VIN # ... by that they can tell what is the correct one to send you.. They also have the program the new one by the VIN so it works properly.
