At 98144 miles, had the PCM replaced -- it had a crack. Cost $894 in June 2005. July 2006 stalling problems and hot AC recurred. Dealer found nothing. Stalled on the way home from dealer. Took it back and they decided it was the PCM AGAIN. Now the car has 114140 miles on it. (This time they said they couldn't see anything wrong with the PCM). Cost $1009. Shouldn't a PCM last more than 16,000 miles? I'm going to be really crabby if I have to replace this again next year.

Before you pay these ripoff artists again, call a NAPA parts store. I just called mine in for a 99 durango with a 5.9, 115,000 miles. It is $289. Part #XTP90147. Make sure you call because they ask a lot of questions & you might need a different one. Mine is not California emmissions for instance. You have to give them your VIN # & approximate mileage & the get you a remanufactured one that is flash programmed for your miles & VIN. You have to pay for it ahead of time & exchange your old one when it comes in. Takes about a week.
I think it's right on the firewall on most models & requires no special tools or testers to install it.
Dealerships are just as bad if not worse than any repair shop for overcharging & misdiagnosing.
And yeah your part only lasting 16,000 miles is ridiculous. Make sure that the vents cirulate air through the engine compartment are not clogged & that wires or cooling hoses have not been misrouted close to it from prior maintenance. These things are sensitive & can lose their flash for a spark plug wire being misrouted too close to it.
You could try pulling it & having it reflashed by a local shop if you want. May take a few phone calls if you can even find somebody. I heard that is $75. If they already troubleshot it & are sure that it must be replaced, call NAPA or somebody that is willing to work with you without charging triple the reasonable cost of repair. Betcha $20 the dealership uses the same place as the parts store as a parts source.
