The good news my faithful old truck is back in the driveway! Hats off to Earnhardt Dodge in Gilbert AZ! I obviously caused the problem. A connector under the dash in the vacinity of the emergency brake pedal had a wire pulled either out or at least back far enough that it did not make connection. I am going to try and attach a picture of the techs description! Thank you to all of you who commented on my posts! Many thanks to Mopar Man for the forum!
What can be learned from this? Hard to say, it cost me $760.00 to get this fixed. Am I sorry I installed my own dash and heater core? No, I can only guess what it would have cost me for the dealer to install the new lower dash and heater core. The wire harnes plugs are tender and need to be respected! Not even sure what I did, just thank God it's back and running, no new parts or computers.
