Thanks so much guys, you guys could have just saved me a huge headache! Is the PCM the "Main" computer in the truck? Where is it located and what does it look like? Do you guys all feel that replacing the part is the only route or would hooking up some sort of fan or air duct to keep the computer cool (as done on normal personal computers) would solve this over-heating problem? Who is to say that once I replace the PCM, the same thing won't happen to the new PCM? I am also a bit worried about the price, since I am not the first owner and bought the car used, will Dodge still cover this cost since my durango only has 65K miles on it? I did, however, purchase a warranty from the dealer when I purchased the truck, but if I never need to use the warranty, I actually get it refunded to me after two years. How much did the labor and part cost? Sorry for all the questions and thanks for being so VERY helpful and I appreciate it greatly. Any more answers would help! Thanks for the replies.
