I need help locating the fuse box(es) in the 2004 ram 2500. Also have a problem with door locks, internal cab lights. Won't work unless ignition is on.Also heater blowing motor works but no heat, directional, heated mirror button and a/c button are not working. All of these happen when trying to hook up new radio.

 

this thing happened to me like 4 days ago... I check every fuse all of them was good... under the fuse box I notice the was a couple of broken wires.. one of then red the one for the lights and everything inside ... After that I don't have to open the switch to have power inside ... I hope this can give u a idea .. srry for my English..

 

I have checked all wires and connections. All seems to be ok.

 

I take off a couple wires because it was rusty.. I replace a couple new wires

 

 

Check all fuses that go to the cluster. If the fuses to the cluster are not bad then an electrical diagnoses of the cluster. There is a line going from the cluster to the radio and I would suspect that you shorted the wire. This is for controlling the lights on the radio.
