slip under the dash and put your feet in the headrest so your looking stright up into the under dash, pull the fuse block (7mm nut driver) and look to the right of the fuse block. there "should" be a chunk of harness thats larger than the rest and roll it around to the other side and see if the insulation has been broken thru.

this happened on my 89 and on a friends 86 T/A. this is a sugguestion, my lights never blew the fuse, just acted real weird.

anything else i did that and it was fine :/ a wire touched a ground down by my radio idk which one it was then they all went out helppp

check your fuseable link down by the starter and check the ground on the core support

darkness878

still no luck with any of this which wire down by the radio is connected to the lights that one touched a ground and then they all went bye bye except there is still power to the headlights its not the switch that is bad

I feel all of your pain I just removed the tbi that was on my 350 and was going to go tpi but decided to put a carb on her and now.....my wiring is going crazy! Headlights work...tail lights and dash lights but my blinkers aren't working (the right turn arrow on the dash stays on..nothing outside though) and the third tail light is out as well. I pulled the buzzer out as well because when you turned on the head lights...buzzer would stay on. I have to rewire my gauges too. the wiring in this car is a cluster. idk

I have the same problem no brake lights tail lights or turn signals. The weird things my gauges act funny when I turn the lights on. As soon as I find the problem or solution I'll post it.

You shorted the lighting circuit with the lighting lead to the stereo (dims display when lights are on). Probably a ground or power feed to head unit burned through and ground ing out in the dash. Strange that the fuse isn't blowing though. Check the radio power fuses.
