Help Needed Truck is possessed...

well i got the truck running again. i had to replace the starter( it was fried), a i believe its called a selinod switch( inside fender on passenger side), and a fuse. i am not sure what any of those things had to do with the a/c fan blowing with no key in the ignition , but the truck runs. thanks everyone for yall input.

Probably a backfeed through the ground . Well at least you got it running

Seems plausible if the short was maintained for a long period of time, to melt the wiring and connector even if it's a solid state controller. Excessive electrical use by any device will cause overheating of the weakest link....

They'rrrre baaaack!!!

Well, i just got through listening to my truck trying to start on it own from inside the house. i run outside thinking its somebody in my truck. the doors are locked, radio is on, the ignition is off and the keys are in the kitchen on the counter. what the hell!!! so power is going to the starter but not the fuel pump, or what ever else is needed to run. i went and got the keys and it started right up. i wonder if it could be a bad ignition switch?

You must have a remote start in the truck. I would disable it until you fix it.

Sounds like a serious short somewhere, allowing the fan to run,and now the starter to be engaged on it's own. My first thought would be the ignition switch(not the key tumbler) and/or wiring going to it. I would change the ignition switch first, checking the wiring carefully for any meltdowns. Could also be a main relay of some sort that is sticking closed in the junction block? A good wiring diagram is going to be very valuable in this case, looking for something that ties into the heater fan motor, and the starter circuit. Could be a fun one, keep us informed as to the progress. Good luck!

I had weird things like this happen to my old chevy truck. It was the remote starter. Do you have on installed?
