O.K. here is the situation, (88T/A) My rear tailights, blinkers, and all four marker lights are not working. I replaced all the bulbs in the rear tailight assembly (made sure they were all properly seated), changed both of the flashers, checked the fuses, checked all the marker bulbs, and still no go. I bought the car to an alternator/ electrical place, they couldn't figure it out either. I can honestly say I don't know sh*t about electrical systems, so I'm consulting with some of the wisest firebird experts in the world. (YOU guys!) Any and all suggestions are appreciated! Thanks in advance!:hail:

 

I would check the headlight switch, seeings how the current has to pass through the switch to get to the tail end of the car. That is the only thing i could think of since you check out everything else.

 

I meant to say the rear brake lights, the tailights work fine. also, the left front headlight is pretty dim, I replaced it, still no improvement. Somehow I think there is a short originating from there?

 

A loose ground may-be!? My head light went dimm also once, and I found a wire that had come off the body.

 

something similar to this happenned to me on my 79 t/a, i ended up having to change the harness in the stearing column(turn signal switch)
just a thought.

 

BINGO, I took it to a real good electrical guy, and yes, it was the blinker assembly. Thanks for all your suggestions. P.S. I've owned a couple 2nd gen's myself, and I think they all have built in electrical problems!

 

all to true.
