99 ram 2500 5.9 gas auto trans
My truck isn't cutting power to the radio, turn signals, and switched power outlet when you turn the key off.
I've replaced the ignition switch and key lock cylinder to no avail.
Is there a relay or something else that could be stuck? I checked my fuse boxes and didn't find anything that clearly stated it would power those.
Any advice is appreciated. Thanks!

 

I'm not seeing a relay in there anywhere.... Is this still the stock system? Do you have the infiniti system?

 

Do you know if the recall has been done for the ignition? If you remove the connector on the back of the ignition switch and inspect the wires, They maybe melted?

 

No on the infinity system. I replaced the head unit about 8 years ago after the stock one died. I wasn't aware of an ignition recall I did check the plug and wires I didn't see anything obvious. As of today I exchanged the switch for a different new one same problem. Bad new parts happen so I thought it was worth a shot.

 

I didn't dig into the column any further than I had to so I guess it's possible it's further down.

 

OK so I tore apart the column. Only found a couple bad wires. Didn't fix the issue. On the plus side my horn now works again. I pulled the radio out and unplugged it. Also didn't fix the issue with it unplugged I checked the switched wire to find it had power with the ignition in the off position. So I think I can eliminate the radio as a source. My Haynes manual shows the black and light grey wire on the ignition switch as supplying power to the turn signals. With the switch unplugged this wire still has power. So I think I can also Eliminate the switch itself. I then poked it as far back under the dash as I could and found it had power there. So I'm thinking the issue isn't in the column wiring either.
I've also noticed that the time delay on the interior lights isn't timing out like they used to its just on.
following the wire it appears to go into the junction box that goes thru the firewall. I'm in the process of removing more dashboard pieces to trace it further.
just giving you guys an update to see if it helps jog your mythical Mopar powers.

 

Also I don't know if this helps. But it also runs a little rough. Specifically said a cyl 3 misfire. However I related this to low battery because after it died while sitting I pulled the battery stuck on the charger gave it a good charge and the rough idle went away.

 

If you remove the harness from the switch and still have power then it's getting power from somewhere else. Do you have a remote start installed? You can look up the wiring here it will give you a better diagram than what's in the Haynes manual.

 

thank you. I will do some digging. No remote starter either. It is possible one was installed at some point. While following wires I found a few wires under the dash that were spliced into at some point then cut off. I did not see anything under there that looked like it didn't belong.
I've also cleaned and checked grounds, replaced a couple grounds that were corroded at the mounting point. I was wondering if the ctm could cause the power to stay on to these things. I'm really grasping at straws there. I don't know a whole lot about what that actually does. Just came across it while searching the forum for similar systems. But most people had the stuff just stop working all together.
Because that is correct that I still have power with the switch unplugged.

 

Look up the wire after the ignition switch(link) that powers the radio and look for anything tapped into it. Radio should only get power at key on(run) and accessory.
