DEAD dash after blue wire mod...PLEASE HELP
I did the blue wire mod for my fan clutch. I used the upfitter pass through wires to gain access to the inside of the cab (the truck does not have upfitter switches). After doing this mod the dash shuts off, no windows, no radio. However, I also get a glow plug open circuit DTC error code on all 8 glow plugs. The blue wire mod has been disconnected with no change.
Here is what happens:
I start the truck everything operates ok. After about 20 - 30 seconds I hear a click from a relay in the inside fuse panel and the gauge cluster dies with no power to the windows and radio. The engine does not die. After cycling the key off and turning the truck back on it does the same thing.
If I just turn the key on and not start the engine the cluster does not turn off and every thing works fine, its only after starting the engine.
Even unplugging the fan clutch I still get the same results.
I also get the P0671 through P0678 errors codes. Even after clearing the codes they return once the keys is cycled and the truck is started again.
I am really stressed out because we are leaving tomorrow with the toyhauler for a camping trip. Any help would be greatly appreciated.
