hi i have a 1986 z28 camaro and i have a third break light problem.i just got new bulbs yes there the right 1s. and i put them in n it didnt work.i tested it with a tester and theres power getting to the third break light (but lights wont turn on)i checked the fuse and the fuse is fine.anybody kno wuts wrong.please help

 

Is this testing voltage at the lamp socket ?

 

If the other brake lights work then he might want to look at the brake switch on the brake pedal. It has two seperate circuits, one for the regular brake lights and one for the third brake light. BTW, I wonder if he is checking them with the hatch open.

 

86 had the high mount on the exterior of the glass IIRC... which is foggy at best, lol.
I thought the wiring to those ran up top like the 91-2 instead of through the contacts at the hatch latch ?

 

Actually, the 86 models had them in the spoiler as well as mounted on the top of the hatch glass. Wonder which one he has. And you are correct about how the wiring for the light on the hatch glass goes.

 

I'd guess hatch alignment. On my 86, there was this little black piece of plastic with metal tabs on it (it was on the bottom of the decklid) that met with a brass piece on the rear plastics (where the hatch motor is)- when you close the lid of the trunk it lines up and transfers power to the brake light. Make sure it's making a good solid connection.

 

i have the third break light on the hatch at the top.i closed the hatch but still nothing.ill check the brake pedal one.where is the ciruits located.r there right behind the break pedal or some where else.and i used the tester that u hook it up to the + on the batery

 

I have an early '87 with the '86 style brake light on top of the hatch(ugh!). I never knew some of the '86 cars got the spoiler brake light?

 

where on the brake pedal is the circuit i have to look for?

 

I had that problem with my RS and the power gets to the light through connectors where the hatch and the body meet. I had a broken strip of copper IIRC and I rigged up something, I can't remember exactly what, to bridge the gap and I was back in business.
