I have a 1985 Cutlass Supreme and the tail lights not dash lights work. I have checked the bulbs and fuses and they are all good. The brake light and turn signal lights work. Any help or even point me in the right directions as I am green to this.

Do any of the side markers, front parking lights work? Headlights high and low?

The headlights high and low beam work and the brake lights and turn signals work just when I turn the headlights on the tail light does not light up. Thanks for the reply

I moved your thread to the Electrical forum, post an intro in the Newbie section when you get a chance. Have you checked your tail light fuse? Were you doing any work previous to the lights quitting?

Did check the fuses and I didn’t do any work and the mechanic that was working on it I don’t believe did anything to it. He brought it to my attention when I picked up from him. Thank you for the transfer.

What was the mechanic working on? You need to start at the fuse or at the tail light and see where the voltage is lost with a meter or test light.

I bet the mechanic is 'SURE' he didn't do it......... LOL

I had this problem on a 70 442. My rear bumper grounds needed cleaned up. Old timer mechanic told me thats how you could tell if all your tail lights are out, Sure enough I cleaned grounds and all worked. I had tested all the lights prior to installing the bumper assy and all worked great. Hope this helps.
