I don't know what Happned but here it goes. 82'Olds cutlass Calais. I started to drive home and suddenly lost my hight heat speed other speeds work then turned on my headlights and there was nothing. No headlights or tailights or dashlights. My brake lights work and the dome light works also my flashers work. I had a similar proglem with a different olds but i just lost tailights and it was a bad ground in the trunk. I haven't lost both lights befoe fron and rear. I tried a different that was working in another car but no change in mine. I was looking for ideas without tearing the whole wiring aprts driving myself crazy. :)
Thanks chris
