02 electrical problems need fast help

I drove to work this morning everything was fine. When I went to go to lunch the truck starts and runs fine but nothing on the dash works except oil pressure and alternator gages. No speedo no tach no lights on the dash anywhere no stereo no A/C no computer can't even see what gear its in. then after driving for a minute or 2 very very hot air starts blowing out of a vent on the passangers side of the 3rd row by the floor. the clock doesn't even work on the dash but it stopped about an hour and a half after I got to work. Any help would be greatly appreciated.

Thanks
Rob

loose and corroded cables can contribute to such electrical system problems.. check your car’s electrical repair manual

Did you ever solve your problem. I have the same thing happening but no one knows how to fix it.
