Ok, recently got a 2006 6.0 with higher miles and some electrical issues, knowing that I got it cheap enough that the cost to fix it won't be able to put me behind.
The main problems:
The speedo acting up
The dash/radio/ac controls/window controls will randomly stop working, and the truck will drive as if its underpowered or starting in second, and it will shift funky, like a manual, running through the gear then backing off before shifting.
The speedo is weird, it starts off way below 0mph then only slow moves while moving. It seemed like it was 5mph low, but its more than that. I had came to a complete stop and parked and the speedo just hung out at about 13 mph. Then I took it to what I guesstimate is about 55-60mph and it got up to about 55mph, then I took it back to down. I went through a couple stops on the way home and it would not go down at each stop, but it would go up when accelerating from the stops. By the time I got home and parked, the speedo sat at about 75mph. While I sat there with AE pulling codes, each time the dash cluster and accessories would die the speedo would drop a little, from 2 to 5 mph. That's about where I stopped there.
The dash issue is weird. I'm assuming its a ground issue, but I have a hard time replicating it. I had gotten it to do it a couple times by pressing the button in the gauge cluster, but then cycling it for several minutes straight. tried all the dash controls, door controls, lights, etc. Tow/haul button too. Really hard to get it to replicate. I'm not sure what all is on the instrument cluster/ radio/ ac control/ window control circuit. No owners manual to check what fuse its on to see if its loose or whatever.
Thanks to anyone who has time to help.
