i have a 1990 300zx and i was driving around the block and it started 2 heat up and smoke was coming out from under the hood on the passenger side of the car and it just shut off in mid drive. i think i had a leak in one of my radiator hoses cuz it was dry when i opened it up but my car still wont start. i changed out the fuse box under the hood because one of the females was burnt up but still nothing. my stereo wont turn on, my windows dont roll up, a/c...nothing! the only things that work are my lights and power seats. any suggestions?
