Mine is actually a 2000 Durango with about 137,ooo Miles
Problem started end of last summer - No Bus.
Replaced the PCM with one from autozone - truck ran fine all winter
Problem started again at the beginning of summer - Replaced the PCM again with a warranty replacement from Autozone.
Now I'm having the probelm again - this time took it to the dealer. They wanted $800 to replace the PCM. Since I was still under Autozone warranty, I replaced with the autozone (Rebuilt by CARDONE).
Now I'm afraid to drive. Want the dealer to do a thorough check, but they tell me that because I replaced the PCM, that there is no info in the PCM to analyze.
Any suggestions ???????
