@rjr1414,
YEP, a sad but true condition unique to the Heavies, from 250 up. This is a diesel?? yes??
If so, the diesel has an interlock somehwere that lets **** like this happen until you take the fuses out and screw with em by rubbing the contacts on sand paper (Real fine grit like 400 or 600) then stick em back in and it usually works for me. If not, you got a short somewhere.
Be thankful you dont have the automatic door locking package which automatically locks the doors while the fuckin thing is running. Its like the HAL 3000 "Im sorry, I cant let you in Dave".
The auto door lock package was in several hundred of 1999-2003 350 D versions with the XLT pqackge of bullwshit fetures.
That one required the fuses to be fully removed whjile travelling but the door fuses also operated some other stuff like the radio (I believe it was the radio)
