Weird and ongoing issue
I've searched all over. Found few people with similar issues but never a final verdict of what was found.
I been having issue with battery draining. More recently, starter engaging without key or while engine running.
Now, my speedo will dance. Cruise shuts down and overdrive light flashing.
Truck runs and shifts fine.
Replaced start solenoid. Seemed to fix but came back.
Replaced ignition switch and harness. Didn't help.
Replaced speed sensor. Didn't fix it.
No engine codes.
When I hook up battery I can here an electrical hum that seems to get louder when I connect the start wire to starter solenoid. I can't narrow it down though.
Any ideas? Or anyone had and solved this issue?
