i went all out and made a new account just to ask for help, so it would greatly appreciated if i could get some pointers.. today my radio, power windows, gauges, rpm tach, headlights, heater, ECT.. (everything electrical) quit working, but the car still runs and drives, i checked all of my fuses. none blown. now im stumped. im thinking the cylinoid, ignition, or something as simple as a dirty ground.. ran outta daylight, so in the meantime looking for a solution

 

More info... as in what year, model ? Turbo , NA ? Might be one of the switchs on the steering column, ignition, turn signal... cant remember the thread, theres a combo switch that seems to cause problems, clean it with contact cleaner, check all the connections to those switches, check your fusable links.

its an 82 280zx. non turbo.

 

Find out what is in common to all those. Did you check the fuseable links? Are you getting power on one side of the fuse?

 

Did ever disconnect the wires that connect to the dash at that hub just above the fuses and forget to reconnect them? and also does the ignition feel loose? If the ignition is the problem don't just buy the first one you see, there are two types of ignitions, they both work, but the key is reversed so you would never be able to put the rest of the car and the ignition on the same key.

 

download fsm from xenon. check the schematic but if that much went out most likely fusilbe link. right side of eng compt. just forward of the battery. if car runs then ignition got nothing to do with it. the other possibility is a ground got loose.
