This is the trick open fuse box should have fuses f1 to f7 no power if not those then i know there is one row that's not getting power take a wire and jump this row from an o the one that has power start the truck leave it like that for bout 10 min remove wire and good to go Ita not the technical way but has worked a 1000 times so i don't mess with it
