I have an 02 ram 1500 4.7 magnum with all the same issues posted here and then some. I've researched multiple forums and websites looking for an answer. To star with, most of my electrical that is supposed work when the ignition is off(interior lights. Door locks.) Do not work when the key is off. When the key is on these features work. But my radio has a mind of its own and only works on occasion. When the radio works all the other things that are supposed to work when the key is off work properly. Recently the blower motor has stopped working. So I replaced the resistor and the blower motor with no affect. I have also replaced the ignition switch(it was burnt on 2 spade clips) and i am still not receiving power to the a.c. control panel. If Anyone could offer more suggestions i would greatly appreciate it.
