i recently got my 86 firebird. and the courtesy lights worked, no problem. but then one day i noticed they didn't go on... none of them. l........... could all of the bulbs burned out at the same time.... bad wiring to everything? what could it be? a fuse? if so, which ones

 

You might want to try the obvious thing first, try and move your actual interior light ****, it could be that it is turned in the off position. Some cars have 1 and some others have 3+ interior lights. It would be odd if all your bulbs went bad at once, you could have had a surge or something.

 

no..... i tried all the obvious things... i turned up the inerior light scroll into i heard and felt the click.... but the lights didn't turn on... the dome light and both the lights that light up where your feet go won't go on...... should i replace a fuse or something? or is it the bulbs?

 

I would go ahead and check your bulbs and see if they are good. sometimes its hard to tell being that they are so small and all. If you want a for sure answer, get yourself a voltage tester/needle bulb and check your sockets out that way. If the voltage tester shows that you have current, it would then surely be your bulbs, if the tester shows no current/bulb does not glow then it will probably be either a loose wire or the fuse. The fuse would be easy to check, just find your fuse box and pull the interior fuse, you should then be able to tell what the problem was, more than likely it is the fuse and you should see a big section of the fuse missing, sort of like this -- -- sorry if I have confused you, good luck and let us know what you find out.

 

Fuse. That's easiest and simplest.

 

DOES your horn work, if not then the fuse is blown, check the fuse, I WILL BET that the fuse blows because of a bad cigurate lighter. Take it out and put it aside and see what happens.

 

Like Ryan said.
